[World Generator] Ocean Only Water World!

So after 10 years of playing me and my friend wanted to spice up things a bit and play in an ocean only world where the whole gameplay would be different since the different available resources. We didn't want to choose between all the available ocean biomes like frozen deep ocean or warm ocean since some of them are very different in terms of default blocks such as coral or ice.

- Reverted back to stock world generation: Added back top layer of ice in most snowy/frozen biomes to make it easier for the player to navigate - Added Underwater Potion to most village chests that grants the player 30 minutes of water breathing upon drinking - Corals, budding amethyst, ice variants, mushroom blocks can be mined with simple tools without silk touch enchantment - Reverse crafting ice, corals, mushroom blocks via crafting table or stonecutter is now possible - Safe world spawn is still risky. Since I'm still horrible at coding and couldn't come up with a fix platform generation during the first time the player spawns in the world, I'll give you pre-tested seeds that have safe world spawn: - Spawn on ice: 906182347964544722 - Spawn on abandoned ship: 6696165159819216322 - Spawn on a floating nether portal: 2589681248334255595
