Brown Mushroom Burch Forest

Almost the whole community was patiently waiting for the reworked birch forests for 1.19. Unfortunately we still have to wait and that's why I propose several variants to thise biome, in order to enrich it. Normally, my proposals won't be difficult to apply in the game for developers. Birch Forest Variant : Mushroom Birch Forest As the name suggests, it's a burch forest with giant mushrooms. But only brown mushrooms to avoid resemblance to dark forests. We can also find small mushrooms on the trees as we've seen with the fanarts during the Minecon.
