Fix bugs and DX issues with bun patch

[Jarred-Sumner]

TODOs for @zackradisic:

• Replace bun patch-commit with bun patch --commit package-name
• Don't copy it into a temporary directory, instead overwrite each file individually in node_modules/package-name with a copy of itself (excluding node_modules, like patch-package). This lets developers test their patches locally before committing them, and avoids the issue where hardlinks can potentially overwrite the cached package. This does not handle postinstall scripts
• Optional, but nice: bun patch --revert package-name
• bun patch --commit needs tests. I am surprised that we merged bun patch when bun patch-commit had zero test coverage.
• bun patch --commit should handle when the patch already exists
• bun patch --commit should work with scoped packages
• bun patch --commit should never cause "Resolving..." to happen indefinitely on install
• bun patch should not be missing from the help menu
• Documentation page

This is probably the biggest blocker for myself and many others from adopting bun.. would love to know how soon this feature could be implemented

I have a PR open now for these changes here: #11858

This is sort of doable with patch-package.
