[desaxce]

Motivation for features / changes

Fixes #7003
When I run tensorboard, I get the deprecation warning, which I don't want:

.venv/lib/python3.12/site-packages/tensorboard/default.py:30: U
serWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pk

ain from using this package or pin to Setuptools<81.
  import pkg_resources

Technical description of changes

I replaced all occurrences of pkg_resources by importlib or packaging.version.

Thank you @desaxce ! Sorry for the delay. I will look into this next week!

So sorry for the delay again. Our CI workflows are currently broken because we seem to have reached the limit of the provisioned VM for GH Actions, and it'll take a little while to resolve this. I'll come back to check this when that is resolved.

python -c "import pkg_resources; print('pkg_resources is available')"
Traceback (most recent call last):
