When the Tag Requests feature is enabled, for new users, Overseerr tries to create a tag in Radarr using the pattern "id - username"
As of the latest Radarr version, tags with spaces are no longer accepted https://github.com/radarr/radarr/issues/11293
They enforce ^[a-z0-9-]+$.
This is causing requests to Radarr to fail with a 400 for new users
"Tag Requests" feature causes request failures with latest Radarr validation
