Disable Stellarity end island

A simple datapack/mod to disable Stellarity's custom generation for the center end island by replacing it with the vanilla end island generation. This allows YUNG's Better End Island and other custom end island packs to properly generate their custom end island features, but please note than any custom end pillar generation may stop Stellarity's Alter of the Accursed from generating properly (or at all)! Please do note that you may have to travel farther than normal after entering an end gateway to see stellarity biomes generate If running as a datapack, make sure to place this datapack **above** the Stellarity datapack in the datapack list!
