Replace distutils.version with packaging.version.path

[pquentin]

Using the pytest plugin on 3.11 (but 3.10 too) gives the following warning:

/home/runner/work/urllib3/urllib3/.nox/test-3-11/lib/python3.11/site-packages/pytest_freezegun.py:5: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives
  from distutils.version import LooseVersion

One option to fix this is to use packaging.version.path: https://github.com/python-pillow/Pillow/pull/4797/files

I was wondering why I couldn't reproduce this, and then couldn't find the pytest-freezegun==0.4.2 version that urllib3 uses, and then noticed it's another library entirely!

This is freezegun, and that warning is from pytest-freezegun => https://github.com/ktosiek/pytest-freezegun

Sorry about that. Thanks @hugovk for the help here!
