There are a few errors thrown by node -- and by our copy-pasted node code -- that confuse users. Add these to the troubleshooting page.

For example, when you try to require() a TS file and it's supposed to be executed as native ESM, the user gets a cryptic ERR_REQUIRE_ESM. When they try to do the same via import() instead of require() -- or node ./index.ts inside a type: module directory -- they get ERR_UNKNOWN_FILE_EXTENSION

Note the ERR_UNKNOWN_FILE_EXTENSION also happens with extensionless files, like require.resolve("mocha/bin/mocha") (which breaks ts-mocha at the moment).

Regarding ERR_UNKNOWN_FILE_EXTENSION and mocha's extensionless entrypoint:
Linking to nodejs/node#41711 where the solution is being discussed. Once a solution is settled upon, ts-node can implement a workaround to mimic the fixed behavior on old node versions.

**Added**

-   Added support for `module=NodeNext`, `module=Node16`, `.mts`, `.cts`, `.mjs`, and `.cjs` file extensions ([#&#8203;1414](TypeStrong/ts-node#1414), [#&#8203;1694](TypeStrong/ts-node#1694), [#&#8203;1744](TypeStrong/ts-node#1744), [#&#8203;1745](TypeStrong/ts-node#1745), [#&#8203;1727](TypeStrong/ts-node#1727), [#&#8203;1717](TypeStrong/ts-node#1717), [#&#8203;1753](TypeStrong/ts-node#1753), [#&#8203;1757](TypeStrong/ts-node#1757)) [@&#8203;cspotcode](https://github.com/cspotcode)
    -   For best results, enable `experimentalResolver` ([docs](https://typestrong.org/ts-node/docs/options#experimentalresolver))
    -   See TypeScript's official documentation: https://www.typescriptlang.org/docs/handbook/esm-node.html
    -   enables mixed-mode projects with both ESM and CommonJS
    -   enables all supported file extensions in TypeScript 4.7
    -   Obeys package.json "type"
-   Added ability to include file extensions in CommonJS imports ([#&#8203;1727](TypeStrong/ts-node#1727), [#&#8203;1753](TypeStrong/ts-node#1753)) [@&#8203;cspotcode](https://github.com/cspotcode)
    -   Enables consistency with ESM, where file extensions are often mandatory
-   Resolves from emitted to source file extensions ([#&#8203;1727](TypeStrong/ts-node#1727), [#&#8203;1753](TypeStrong/ts-node#1753)) [@&#8203;cspotcode](https://github.com/cspotcode)
    -   Must enable `experimentalResolver`, will be enabled by default in a future version ([docs](https://typestrong.org/ts-node/docs/options#experimentalresolver))
    -   Typechecker requires importing the *emitted* file extension; ts-node resolves correctly to the *source* file.  E.g. `import "./foo.js"` will execute `foo.ts` See also: [TypeScript issue #&#8203;37582](microsoft/TypeScript#37582)
    -   If typechecking is disabled, you can also use *source* file extensions.  E.g. `import "./foo.ts"`
-   Added `experimentalSpecifierResolution` ([#&#8203;1727](TypeStrong/ts-node#1727), [#&#8203;1753](TypeStrong/ts-node#1753)) [@&#8203;cspotcode](https://github.com/cspotcode)
    -   the same as Node's `--experimental-specifier-resolution` ([Node docs](https://nodejs.org/dist/latest-v18.x/docs/api/esm.html#customizing-esm-specifier-resolution-algorithm))
    -   can also be specified in `tsconfig.json` for convenience, to avoid the CLI flag
    -   allows omitting file extensions in ESM imports, plus a few other CommonJS-style conveniences
-   Adds `diagnostics` property to `TSError`, with array of TypeScript diagnostic objects from the compiler ([API docs](https://typestrong.org/ts-node/api/classes/TSError.html)) ([#&#8203;1705](TypeStrong/ts-node#1705), [#&#8203;1706](TypeStrong/ts-node#1706)) [@&#8203;paulbrimicombe](https://github.com/paulbrimicombe)

**Changed**

-   Renames option `experimentalResolverFeatures` to `experimentalResolver` ([docs](https://typestrong.org/ts-node/docs/options#experimentalresolver)) ([#&#8203;1727](TypeStrong/ts-node#1727)) [@&#8203;cspotcode](https://github.com/cspotcode)
-   Internal change to ESM loader for compatibility with forthcoming node versions: returns `shortCircuit: true` ([#&#8203;1714](TypeStrong/ts-node#1714), [#&#8203;1715](TypeStrong/ts-node#1715)) [@&#8203;cspotcode](https://github.com/cspotcode)
-   Performance: Optimize filesystem stat calls in ESM loader and new CommonJS resolver ([#&#8203;1758](TypeStrong/ts-node#1758), [#&#8203;1759](TypeStrong/ts-node#1759)) [@&#8203;cspotcode](https://github.com/cspotcode)

    -   Switches to "trace-mapping" for underlying source-map parsing ([#&#8203;1729](TypeStrong/ts-node#1729)) [@&#8203;cspotcode](https://github.com/cspotcode)

**Fixed**

-   Fixed bug where REPL `.type` command was not showing any type information when using TypeScript nightly builds ([#&#8203;1761](TypeStrong/ts-node#1761), [#&#8203;1762](TypeStrong/ts-node#1762)) [@&#8203;cspotcode](https://github.com/cspotcode)
-   Correctly suppress "Custom ESM Loaders" warning on newer node versions where the warning's prose changed ([#&#8203;1701](TypeStrong/ts-node#1701)) [@&#8203;cspotcode](https://github.com/cspotcode)
-   Fixed REPL bug where function signatures could not be entered across multiple lines ([#&#8203;1667](TypeStrong/ts-node#1667), [#&#8203;1677](TypeStrong/ts-node#1677)) [@&#8203;d9k](https://github.com/d9k)
-   REPL treats unparenthesized object literals as objects, instead of as block scopes ([#&#8203;1697](TypeStrong/ts-node#1697), [#&#8203;1699](TypeStrong/ts-node#1699)) [@&#8203;jhmaster2000](https://github.com/jhmaster2000)
-   Fixed bug where `preferTsExts` combined with third-party transpiler hooks could disrupt `nyc` code coverage ([#&#8203;1755](TypeStrong/ts-node#1755)) [@&#8203;cspotcode](https://github.com/cspotcode)
-   Fixed bug where `file://` URLs in stack traces did not always use percent-encoding ([#&#8203;1738](TypeStrong/ts-node#1738), [#&#8203;1726](TypeStrong/ts-node#1726), [#&#8203;1729](TypeStrong/ts-node#1729)) [@&#8203;cspotcode](https://github.com/cspotcode)
-   Fixed bug where v8-compile-cache-lib did not correctly unhook itself ([#&#8203;1717](TypeStrong/ts-node#1717), [#&#8203;1718](TypeStrong/ts-node#1718), [#&#8203;1719](TypeStrong/ts-node#1719)) [@&#8203;cspotcode](https://github.com/cspotcode)
    -   This internal dependency is used to speed up loading the TypeScript compiler

**Docs**
