Some mobs do not spawn in river biomes

Zombies, spiders, creepers and skeletons spawn in river biomes in java, but in Bedrock Edition they don't spawn in water depths, they have not spawn weights, this is an old issue, please fix it

Note that these mobs spawn in shallow water, but not deep water, which requires Java parity.

Mojang can add       "monster": {}, tags in the biome files for river biome to solve the problem
