Python 3.8 is End-of-Life (EOL) as of 2023-06-27 as stated in
https://devguide.python.org/versions/ and
https://peps.python.org/pep-0537/

By dropping support for Python 3.7 and requiring Python 3.8 or higher
it allows python-gitlab to take advantage of new features in Python
3.8, which are documented at:
https://docs.python.org/3/whatsnew/3.8.html

BREAKING CHANGE: As of python-gitlab 4.0.0, Python 3.7 is no longer
supported. Python 3.8 or higher is required.
