End update 1.18: Ender peaks

A biome, the Ender peaks, a mountainous biome that would have the new grass and a new structure, the Purpur temple, a very large structure that when it spawns, it takes up almost the intire mountain. In it would be many Ender zombies and at the end, the Ender lurker, a new mini-boss. The temple would be the new place to get the elytra, the shadow Purpur blocks, the blocks that cover the entire temple are unbreakable, they would look like Purpur bricks but in the cracks are a dark purple. The only way in would be a single entrance that can be buried in the mountain. The mini-boss would be 4.5 blocks tall, look like an Enderman, would have thicker arms, and deal 15 damage without armour. There would be a gateway block to teleport you out of the temple. The temple would be a giant maze.
