Revert ES Migration add permission data to notes documents (2nd attempt)

What does this MR do?

Revert !55118 (merged)

There are 432 Note documents that are not migrating in staging. This is due to the Notes being on Commit objects which are deleted. An example of these notes can be found in staging

What will happen upon revert?

The ee/app/workers/elastic/migration_worker.rb will no longer see a migration file to run and will stop attempting to index the 432 documents. We have already reverted this once and saw it successfully stop running the migration. There should not be any impact to indexing new data in production (tested in staging by adding new text to a file and it was immediately available via search).
