馃崚 Silently fail when 404'ing on featured tags
Some server software like Akkoma/Pleroma don't implement this endpoint, annoying users of these servers. Instead of violently warning that we 404'd, just silently fail. This is OK as the code will fall back to not showing any tags.
(cherry picked from commit 5236b6af)
