Replace deprecated SafeConfigParser with ConfigParser

[alexandre-perrin]

Situation

Currently, with python <= 3.11, a deprecation warning is issued when instantiating SafeConfigParser object.

 SafeConfigParser class has been renamed to ConfigParser in Python 3.2. This alias will be removed in future versions. Use ConfigParser directly instead.

In python 3.12+, it now fails as it has been removed and this library can no longer work on Ubuntu 24.04 as it uses python3.12:

$ python setup.py --command-packages=stdeb.command bdist_deb

Resolution

Replace SafeConfigParser with ConfigParser or handle pre python3.2 configparser version.

Ok after cloning current main branch, I see this has already been done.
However, it seems that it hasn't been released yet.
Am I wrong?
