Add support for Django 4 (#24)

* Use path instead of url to support Django 4

The old way of defining urls in DJango is no longer supported in Django 4.0.

This commit replaces the regular expression based paths by the more modern path method, and also adds app_name in the urls file to allow usage with URL namespaces.

* Increase version

Altered major version because old versions of Django cannot be supported anymore.
