## PR text
I realized that the tag changes we introduced in #1907 would be breaking for people who use the unleash-server package and implement their own endpoints on top of it (as we do in unleash-enterprise).
This change makes it possible to still use the old tags. However, these tags are purposefully not added to the root schema or the list of OpenAPI tag types. Any of our endpoints still using them (I think there is one in Unleash enterprise, see ivarconr/unleash-enterprise#109) should switch over when possible.
