Remove `user_details.provisioned_by_group_at` column
We added this column recently !112083 (merged) for implementation that we have been working on and only plan to apply in production. As per #406266 (closed)
we decided to use another column instead of user_details.provisioned_by_group_at
.
Remove this column as per the guide https://docs.gitlab.com/ee/development/database/avoiding_downtime_in_migrations.html#dropping-columns and remove related code added in !112083 (merged)
