ci: Use patch api (django CMS 4.1+)

[fsbraun]

Description

This PR implements the patching API for django CMS v4 (https://github.com/django-cms/django-cms/pull/7439) for djangocms-versioning in a backward compatible way.

The patching API requires functions, methods, or properties that are patched to be marked by the @patch_hook decorator. Trying to patch functions, methods, or properties that are no marked will raise an ImproperlyConfigured exception.

This is a precaution to ensure developers of the core are aware of patch hooks and to prevent injection of side-effects in the future as far as possible.
