New Villages and Nether Villages

New villages for more biomes e.g. cherry, mangrove, dark oak,  pale oak, dappled forest.

Also have village systems in the nether, with either maybe piglin-villager hybrids/a new mob or with hoglins. Main currency could be a new ore such as ruby that can only be traded for or mined in the nether but with the same rarity as emeralds, as gold would be too easy for a village system. They could have their own nether plants farming system, or have more professions with different trades.
