Migration from pkg_resources (deprecated)

[Schplaf]

Hello,

cli.py uses pkg_resources, however pkg_resources is deprecated as an API. The pkg_resources package is slated for removal as early as 2025-11-30.

A way to fix it is to use importlib.metadata instead. For instance, this patch should work:

Probably a better patch:
