[demographics]: Django 4.2 Upgrade

[awais786]

Under the effort of Django4.2 upgrade complete all of the following steps to complete the upgrade.

• [x] Update tox & Github action workflow using modernisers to add support for Django 4.2
• [x] Remove any versions of Python earlier than 3.8 from tox.ini, and GitHub Actions workflows.
• [ ] Update the pinned Django version in the requirements to Django==4.2
• [ ] Run make upgrade to update all dependencies for Django 4.2.
• [ ] Run and verify all tests are passing in the CI for both Django 4.2 and Django 3.2 to contain backward compatibility.
• [ ] Run available code-mods to fix the failing tests.
• [ ] Add conditional checks wherever needed to still have support for Django 3.2.
• [ ] Update the repo support field in the IDA Upgrade Sheet.
