feat: add support for Python 3.12

[jackwotherspoon]

Add that Python Connector officially supports Python 3.12

Closes #900

[jackwotherspoon]

Python 3.12 no longer comes with setuptools (i.e pkg_resources) as mentioned in https://docs.python.org/3/whatsnew/3.12.html

This causes issues with pytds driver that imports pkg_resources in its __init__.py

.nox\system-3-12\Lib\site-packages\pytds\__init__.py:69: in <module>
    import pkg_resources  # type: ignore # fix later
E   ModuleNotFoundError: No module named 'pkg_resources'

Opened denisenkom/pytds#157 PR as a potential fix.

[jackwotherspoon]

python-tds PR has been merged, should wait till release of 1.15.0 next month prior to merging this PR

Do we need to add a note about pytds? Probably not?

@enocom No we will just wait till the new release of pytds driver and the version bump in this repo should then make these builds green.
