fix(plugin-search): delete does not also delete the search doc (#12148)

The plugin-search collection uses an `afterDelete` hook to remove search
records from the database. Since a deleted document in postgres causes
cascade updates for the foreign key, the query for the document by
relationship was not returning the record to be deleted.

The solution was to change the delete hook to `beforeDelete` for the
search enabled collections. This way we purge records before the main
document so the search document query can find and delete the record as
expected.

An alternative solution in #9623 would remove the `req` so the delete
query could still find the document, however, this just works outside of
transactions which isn't desirable.
