TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension "" for ... tsc

[andreialecu]

This was probably introduced by #3667 - at least it made it more visible (cc @merceyz)

Here's a repro:

corepack enable npm
cd `mktemp -d`
yarn init -2
yarn set version from sources
yarn config set pnpEnableEsmLoader true
yarn
NODE_OPTIONS="--loader $PWD/.pnp.loader.mjs" yarn add test@andreialecu/nestjs-sentry#aa/refactor

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension "" for /private/var/folders/9p/k1yqxx0d7rn1nlztg_wm7sbw0000gn/T/xfs-1ff1050a/node_modules/typescript/bin/tsc
    at new NodeError (node:internal/errors:371:5)

Note that in my actual project I'm not adding NODE_OPTIONS="--loader $PWD/.pnp.loader.mjs" manually. Yarn does that itself for some reason which is probably related to heuristics where it finds that one of my dependencies needs it.
