Add ModuleType as a possible type to URLResolver.urlconf_name (#1891)

* Add `ModuleType` as a possile type to `URLResolver.urlconf_name`

According to code comment:
It may also be an object with an urlpatterns attribute (i.e. a module object)

* Update resolvers.pyi

* Remove `None` as a possible value
