Problem

Currently, we are doing some tag cleanup during the ingestion, which duplicates the work done in the catalog.

Description

We should remove the tags cleanup step from the ingestion server after the database audit (https://github.com/WordPress/openverse/issues/1557) is completed.

~~Adding here that we should also run a tag cleanup that would remove the incorrectly encoded tags to fix #1303 before removing the tags clean up process.~~ This issue was mixing the tags and the URLs. It now only refers to the URL cleanup.
