Create endpoint to return list of all emote sets
In V5, it is possible to get all emotes that existed on the platform via both
"get-chat-emoticons-by-set" (when no sets are provided)
This currently has no equivalence in Helix, and also has no listed migration path.
This request is to create an endpoint that returns the list of all emote sets (and ideally their last update time) such as "get-all-emote-sets". This would allow a user to then get all emotes via the "helix get-emote-sets" endpoint that currently exists.
