Run permission labels through translation on the permission management template (#11923)

Since `{% trans some_variable %}` cannot be handled by makemessages, we also need to ensure that any string that arises from Wagtail's native permissions, such as "Can access Wagtail admin" or "Can view", exists somewhere in the python code as a `_("...")` value.

Fixes #5341
