Add a way to see what biome you're in

Similar to how Bedrock has a way to toggle showing the world coordinates, there should also be a way to toggle showing the current biome you're in. Java already has this ability in the F3 screen, so there's already a precedent for it. This would make things such as figuring out what type of ocean biome you're currently in or figuring out whether or not you've entered the deep dark much easier, without the need of using external seed analyzing programs.
