[UsamaSadiq]

Description

Under the effort of Django 4.2 Upgrade, complete all of the following steps to complete the upgrade.

• Update tox & Github action workflow using modernisers to add support for Django 4.2
• 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.

Although this repo hasn't yet been updated to Django 4.2 but since it has been deprecated so we can close this issue without making any change.
