Classic and XDevAPI connector Python source
distribution (sdist) name was updated to comply
with [PEP 625](https://peps.python.org/pep-0625/).

Additionally, setup.py was updated to make sure
metadata files are correctly included in the sdist
when generated. Ultimately, to make the sdist pip
installable.
