Mangrove planks, stairs, and slabs are named incorrectly

Mangrove wood planks, stairs, and slabs are named incorrectly, they should be named "Mangrove Wood Planks", "Mangrove Wood Stairs" "Mangrove Wood Slab" to match the other overworld wood types.

I'm aware that since the planks from the nether aren't actually wood, this doesn't apply to them
