Since HttpResponse.text uses @cached_property, add it in allowlist.txt

It was previously in allowlist_todo_django52.txt because
it is a Django 5.2 addition, and was not implemented in django-stubs
yet.

It is now in allowlist.txt because it uses @cached_property,
which stubtest currently doesn't handle
