feat!: Django 4 - Githubissues

Upgrade from Django 3.2 to Django 4.2

Upgraded all Django-related libraries, and reorganise where they sit, i.e., move the ones also installed by Rapid Router to the common package
Updated our custom security middleware to continue setting the X-XSS-Protection header to 1 as Django stopped doing it
Renamed the captcha library to django-recaptcha
Updated all URLs to use re_path instead of url
Extended Django's UserAdmin class to be able to still add custom Django admin panel actions to it
Updated the two_factor templates that we overrode a while back to customise them, to match the new latest version of the library
Updated the two_factor views that we overrode a while back to customise them, to match the new latest version of the library
Targeted Django admin panel's logout button using the form action instead of the href of the anchor which got updated to a button by Django
Replaced force_text with force_bytes
Replaced ugettext with gettext
