Add setuptools to fix failing tests on Python 3.12

Like #1962 but for Python 3.12

• Fixed whoosh test failures with Django 5.0 #1962

I guess a new pysolr release is needed to fix the issue on Python 3.12.

[cclauss]

Just needed setuptools on Python 3.12.

python3.12/site-packages/pysolr.py", line 14, in <module>
      from pkg_resources import DistributionNotFound, get_distribution, parse_version
  ModuleNotFoundError: No module named 'pkg_resources'

This was done in pysolr repo in django-haystack/pysolr#425

Thanks, what about squashing commits?

[cclauss]

I almost always Squash and merge unless the individual commits tell a story that is vital to preserve.
