pkg_resources is deprecated as an API

[benfiedler]

After a recent pip install of salt-pepper==0.7.6 on a python3.10 system, running pepper provides this warning message -

venvs/salt-pepper/lib/python3.10/site-packages/pepper/__init__.py:4: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81. import pkg_resources

I have pinned to Setuptools 80.9 but a long term solution would be ideal.
