Add support for Django 4.2

[gherceg]

Python 3.7 has been EOLed, so remove that and run against newer versions of Python as well (3.10 and 3.11).

And in anticipation for Django 3.2 being EOLed in April 2024, we should update tests to run against both 3.2 and 4.2 LTS.

I'm planning to create a separate PR officially adding support for 4.2 until I've done some due diligence, but passing tests is a promising start.

Update: I read through breaking changes introduced in 4.0 and feel confident that django-prbac is not relying on any of these. I'm thinking of updating the allowed django versions in this PR as well. Any thoughts @millerdev?

:+1: Sounds good to me.

I realized that the "tests passing on 4.2" before was due to pip install -e . uninstalling 4.2 and installing 3.2 based on the requirements of django-prbac:

(test-prbac) ⏺ code/django-prbac % pip install -e .                                                                                                        I

There were a couple of changes in Django 4 that needed to be addressed here:

• django.conf.urls.url has been replaced by django.urls.re_path|path
• django-admin.py has been replaced by django-admin
• when an unsaved db object attempts to access a foreign key relationship, a ValueError exception is raised

I've addressed these in this PR as well, so tests for 4.2 now pass.
