Deploy to NPM with sourcemaps OR don't compile with sourcemap refs.

monaco-editor version: 1.10.1
Browser: Chrome
OS: OSX

Steps or JS usage snippet reproducing the issue:

Bundling tools (such as webpack or parcel) attempt to load source-maps when referenced within JS files - and throw warnings when not found.

The monaco-editor source that is published to NPM contains references to source-maps that are not included within the package.

For example, here is a sample warning (of hundreds) emitted by Parcel when trying to bundle monaco:

⚠️  Could not load existing sourcemap of "../../node_modules/monaco- 
editor/esm/vs/language/json/_deps/vscode-json-languageservice/utils/json.js".

This is pointing to the following file, which contains this reference as the last line:

//# sourceMappingURL=json.js.map

The json.js.map file that it is expecting as a sibling has not be included on the published NPM package.

SOLUTION:

1. Either include the sourcemap files in the published package, or
2. Don't transpile with the sourcemap references.

Thanks! 🍰
