CI fails with python 3.12

[MiWeiss]

The CI fails with python 3.12. I have not yet looked into why; it might be a trivial fix.

I won't be available to have a look at this; if anyone fancies having a look, please feel free to open a PR :-)

Hi, I believe it's because pkg_resources has been deprecated.

https://setuptools.pypa.io/en/latest/pkg_resources.html

Traceback (most recent call last):
  File "/opt/hostedtoolcache/Python/3.12.2/x64/bin/docstr-coverage", line 5, in <module>

As a note: it also makes my pre-commit fail

Should be fixed with #139 (newly opened PR)
