Change list-of-POSIX-paths to list-of-strings in yield of iterate_pip_pkg_record() function

[michaelweinold]

This hopefully solves:

• Build fails with "Object of type PosixPath is not JSON serializable" jupyterlite/xeus#113

[DerThorsten]

lgtm, the failing test seems unrelated

[michaelweinold]

Once this is merged and a bugfix-release published - is it sufficient to specify the version in the build-environment.yml?

I am a little confused because empack is being installed in the mamba environment where the packages from environment.yml are all added.

@DerThorsten, is there any way a bugfix release could be made before mid-September. We were hoping to switch from Pyodide to the more performant XEUS kernel - but this is currently blocking us 🙈

[DerThorsten]

@michaelweinold Sure, for releases, I usually summon @martinRenou :)

The test failure boils down to this:

Traceback (most recent call last):  File "main.py", line 6, in <module>
    from scipy.linalg import lapack

Did we upload a new version of scipy/numpy recently?

Definitely unrelated to this PR though

Thanks!

I had to revert this PR as it seems it's breaking pip packages: #105

Will release a patch release right away
