This PR undoes the migration for removing the facebook_url column from the CourseOverview table, introduced in https://github.com/edx/edx-platform/pull/11326.

We need a 2-phase removal of this column in order to support rolling out to multiple workers on prod. Plan:

  • Remove the facebook_url field from the django models, but do not remove the column from the underlying table.
  • Release this to production. With this 1st release, old workers that expect the column to be there will not break.
  • In a subsequent release, add a migration to remove the facebook_url from the underlying table. By this 2nd release, old and new workers will not expect the column to be present.
