Downgrade from Django 4.0 to Django 3.2

Unfortunately wpull only supports Python 3.6, see

- ArchiveTeam/wpull#404
- ArchiveTeam/wpull#451

Django 4.0 dropped support for Python 3.6, see

https://docs.djangoproject.com/en/4.2/releases/4.0/#python-compatibility

In order to integrate wpull with the viewer application, we need to
downgrade the viewer Django version from 4.0 to 3.2.
