simple_history: integration templates don't work with simple_history >=3.8.0

[cfra]

What version of Unfold are you using?

0.46.0

What version of Django are you using?

5.0

Describe your issue

simple_history added pagination for the change list in django-commons/django-simple-history#1277 which made it into release 3.8.0.

The templates overwritten by django-unfold don't reflect this yet, resulting in a claim of no changes having been found, because they are looking for historical_records in the template context that has been replaced by page_obj.object_list as can be seen here
