Structures' spawn biomes fix

This datapack fixes the list of biomes where various structures spawn in Minecraft. In the original version of the game, some structures generate only in a limited set of biomes, which reduces the diversity of the game world.

What exactly is fixed

• Plains villages - now spawn not only in plains and meadows, but also in forests and sunflower plains
• Savanna villages - additionally generate in savanna plateaus
• Taiga villages - expanded to include old growth pine and spruce taigas
• Pillager outposts - now spawn in all village types, including new ones

These changes make the game world more diverse and interesting to explore.
