[Bug?]: fs.rm is broken with recursive option in yarn 3 pnp, node >= 20.12.0

Self-service

• I'd be willing to implement a fix

Describe the bug

When using fs.rm with recursive: true (or its sync, async version rmSync and fs/promises#rm), there's an error of TypeError [ERR_INVALID_ARG_TYPE]: The "list[2]" argument must be an instance of Buffer or Uint8Array. Received type string.

To reproduce

1. Clone reproduction repository https://github.com/jwoo0122/yarn-3-node-20-test
2. Run yarn node test.js

Environment

System:
    OS: macOS 14.2.1
    CPU: (10) arm64 Apple M1 Max
  Binaries:
    Node: 20.12.2 - /private/var/folders/l4/c6zfhs7d0zq4lm_fgkrlml1c0000gq/T/xfs-d0b6f4b6/node
    Yarn: 3.8.1 - /private/var/folders/l4/c6zfhs7d0zq4lm_fgkrlml1c0000gq/T/xfs-d0b6f4b6/yarn
    npm: 10.5.0 - ~/.nvm/versions/node/v20.12.2/bin/npm
    bun: 1.0.27 - ~/.bun/bin/bun

Additional context

I found this doesn't happen on node 18. recursive option of fs.rm uses readdirSync, and on Node 18 we use pure node fs module but on Node 20 we use pnp patched version.

This error happens when the patched readdirSync is used internally, by converting the result from Buffer to string with NodePathFS.mapToBase. It also means that pnp patched readdirSync does not respect the encoding option, which is buffer in internal/fs/rimraf. According to Node.js Docs if the encoding option set to buffer, the result should be an array of buffer.

From Node 20.12.0, ESM facade is build when it's necessary. Before this change (like, <=Node 20.11.1) when the fs module is imported, internal/fs/rimraf was also resolved.

In .pnp.cjs of yarn 3.8.1, we do require('fs'). At this point fs is not patched at all. So this happens:

• If you're using Node.js <20.12.0, internal/fs/rimraf is resolved by getESMFacade. It uses non-pnp version of fs.readdirSync (original version), which can handle encoding option. No Error.
• If you're using Node.js >=20.12.0, internal/fs/rimraf is not resolved. After we meet the code in user script which actually use internal/fs/rimraf (e.g fs.rmSync), node resolves the module. At this point we already done the preloading of pnp patching, so internal/fs/rimraf uses pnp-patched version of fs.readdirSync, which doesn't handle encoding option. But internal/fs/rimraf wants it to return the result as buffer array, so there's an Error.

Looks like that yarn 4 NodeFS.readdir(Sync) supports the options correctly, but not for <3. So this error happens when you use Node.js 20.12.0 or later && yarn 3.x or earlier.
