Upgrade to Django 5.0 (#211)

I've also regenerated the scaffold project and ported any changes to it
over to the project here (which turned out to only be docs URL changes
this time).

See:
https://www.djangoproject.com/weblog/2023/dec/04/django-50-released/
https://docs.djangoproject.com/en/5.0/releases/5.0/
https://docs.djangoproject.com/en/5.0/howto/upgrade-version/
