Try to require pnp from `baseDir` if it is null

[lmiller1990]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch resolve-package-path@4.0.3 for the project I'm working on.

Correctly grab pnpapi if the Yarn 3 project is not the same as the process.cwd(). This is useful because this module executes require('pnpapi) as soon as it is required, and that cwd may not necessarily be the one with the project.

Here is the diff that solved my problem:
