New Golems (Gold Golem, Diamond Golem)

I think that we should be able to use the other rare metals in minecraft to make different types of golems, while maybe having to use an item frame to make them specialized. I’d like to see a gold golem made with a bow in an item frame, so it would shoot arrows, and a diamond golem made with a diamond sword so it would wield a sword in its completed form. I’d like to see them spawn in villages of certain prosperity, so if you get the villages from a village of a certain size leveled up you may start to see gold golems, and an even larger village with everyone maxed out you may see diamond golems naturally spawning.
