Use assertRegex instead of assertRegexpMatches for Python 3.11 compatibility.

The deprecated aliases were removed in Python 3.11 in python/cpython#28268 . Fixes below warnings that are error now.

Thanks for the review. The project had Python 2.7 classifier in setup.py. So I thought Python 2 is supported and added fallback. I guess it's good to drop the classifier and also add python_requires https://packaging.python.org/guides/dropping-older-python-versions/

Good call on python_requires, it doesn't hard block which is nice =) Dropping the classifier also sounds good 👍

I don't have capacity to pick this up at the moment but I should be able to do that by the end of next weekend

I've updated the classifiers and released 3.3.1. Thanks for all your work @tirkarthi!
