If we are allowing nullable, lets actually use nulls then - otherwise we
don't really need to alter the table in the first place.

Review Comment:
We probably should refresh the bundle and [relist the dags from
disk](https://github.com/apache/airflow/blob/bf0bfe9dc1f3812989acfe6ed7118acf9ba5b586/airflow-core/src/airflow/dag_processing/manager.py#L579)
instead of querying the db.
I think we can just refresh here, relist, and add, but it'd be worth giving
it a bit more thought to make sure we aren't impacting other stuff by doing so.
