Remove tag filtering steps during ingestion

[AetherUnbound]

Description

Blocked by #4541 and #3925 more broadly.

Per #4465 and the clarity gleaned in other places within the project, we are moving towards the catalog database serving as a "data warehouse". Operationally, this means we intend to store as much information as we can in it and filter out low quality or inaccurate data during the data refresh process. As such, once the ingestion server is removed and we have data filtering in place, we should remove the steps that occur during provider ingestion which would remove denylisted tags.

Specifically, we can remove the step here that would remove tags (the _tag_denylisted function):

openverse/catalog/dags/common/storage/media.py

Lines 296 to 300 in 47fe5df

	return [
	self._format_raw_tag(tag)
	for tag in raw_tags
	if not self._tag_denylisted(tag)
	]

The filtering of denylisted tags will happen entirely in the data refresh process instead.
