pytest version 7.2.0 broke pytest-parallel

• a detailed description of the bug or problem you are having
  I have CI that is using pytest and pytest-parallel to speedup execution times.
  Yesterday CI passed without any issues, but toady it failed with error log:

• pytest and operating system versions 7.2.0 | Ubuntu 22.04.1 LTS

I found that in newest version py.py file was added, and I think that this prevents pip install pytest-parallel from installing py library.
Running import py does in fact import py.py file.

See kevlened/pytest-parallel#118 and #10420 for some context. Not a pytest issue.
