Attempting to upgrade Python to 3.12 so that ppa-nlp can be used as a dependency

[laurejt]

An upgrade to Python 3.12 is not possible because of eulxml which relies on pkg_resources which Python 3.12 has removed from the standard library (and to setuptools). That said, the use of pkg_resources is deprecated and importlib-based alternatives should be used instead (source).

Per @rlskoeser's discussion with Emory, we should consider creating a hard fork of eulxml in the future.

For now, I will alternatively try adding 3.11 support to ppa-nlp.
