Woodland Mansions should use wool stairs

The Woodland Mansion has red carpet running through its hallways, to make the new features feel like they are integrated into the game, the stairs in Woodland Mansions should be made from red wool stairs to match this carpet. Additionally, there are several bedrooms in woodland mansions, the beds in some (or all) of these rooms could be updated to use slabs instead of carpet on top of wool. Other structures that could use wool slabs or stairs: - Ancient Cities - Villages - Pillager Outposts
