Drops Python3.7 support

[sobolevn]

Hi!

The "why" about these changes:

1. First of all, pkg_resources is now almost-deprecated:

 ../usr/local/lib/python3.11/site-packages/punq/__init__.py:27
  /usr/local/lib/python3.11/site-packages/punq/__init__.py:27: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
    from pkg_resources import DistributionNotFound

2. It is a 3rd party package that was not listed in dependencies.
3. Python3.7 is dead now, so we can drop it. But, we have to list Python3.11 as supported and tested
4. I've also updated all dependencies (whichout changing their bounds) and I've updated most github actions
5. I've added a change log entry and bumped the version number
