Update 1.5 (Fixing inconsistencies)

• To maintain a more vanilla-like look, many coniferous biomes no longer generate leaf litter, a few still remain for now
• Added animal farm variants compatibility in a bunch of biomes, now Biomes O' Plenty, Environmental and Atmospheric are complete
• Fixed a bug with gray particles from Windswept pine leaves (1.20.1)
• Improved the color of the fallen leaves from Nature's Spirit willow leaves
