Add a variant of sulfur cave for the end

In the End dimension should have a new biome where can generate the end pools with the potent purpur, this end pools would give the player levitation and withering. This biome would spawn shulkers, endermite and a new enderman variant (the spectator), this mob works like the enderman, but give more damage and also drops the new "enderite" (a new ore that only generates in this biome and is stonger than netherite). This biome would be generated with diamond ores, enderite ores, pyrite (replacing sulfur, having a darker gold coloration), calcite (surrounding the biome) and Silicate rock (have a colour bettwen endstone and sulfur, and can be made with 8 endstones and 1 amethist or obsidian), the ores would generate in the endstone that generates inside the biome. (the biome was inspired by the sulfur moons Europe and Io)
