Add game detection requirement to claim-your-game prerequisites (#8341)

* Add game detection requirement to claim-your-game prerequisites

Documents that Discord must have an official record of a game before
it can be claimed, explains that recognition grows with playerbase and
playtime, and clarifies that Rich Presence is separate from automatic
game detection. Directs developers to the Step 2 dropdown as the
definitive way to check whether their game is eligible.

* Review updates.
