Overhaul of the Biome Generation System

For some time now, there has been an issue causing mini-biomes to spawn all over the world, which makes exploration tedious when trying to find biomes of a decent size. In addition, in Minecraft Java Edition, some biomes generate differently than in Bedrock Edition, causing them to be smaller. Some examples of these biomes are snowy mountains, sulfur caves, and dappled forests. To solve this problem, it would be good to have an overhaul of the biome generation system, which would prevent the appearance of small biomes, achieve complete parity in biome generation, and improve certain aspects such as rivers.
