No ultimate rarity

[AzureAaron]

The Rarity enum does not have an entry for the ULTIMATE rarity, instead the legacy SUPREME rarity exists in its place. The supreme case should be deprecated for removal and the ultimate rarity should be added.

Perhaps the SUPREME rarity shouldn't be deprecated for removal since the official SkyBlock Resource Pack has a tooltip background asset for it... I thought it was removed from the game but I guess it still exists internally.
