Title：Add a big update for The End dimension

The Overworld and Nether have received many large updates over the years, but The End hasn’t gotten meaningful new content for a very long time. Right now the End only has endermen, end cities and the Ender Dragon. It’s boring after beating the dragon once. I hope Mojang can make an official End Update: add new End biomes, unique blocks, new mobs, new structures and endgame resources to enrich the End exploration experience for Bedrock Edition players.
