Prepare a package for patching (inspired by a similar command in Yarn).
This command will cause a package to be extracted in a temporary directory intended to be editable at will.
Once you're done with your changes, run
pnpm patch-commit <path> (with
<path> being the temporary directory you received) to generate a patchfile and register it into your top-level manifest via the
pnpm patch <pkg name>@<version>
The package that needs to be patched will be extracted to this directory.
Ignore existing patch files when patching.
