1.17 fool's gold

This would be a new ore that is as common as coal there is a 50% chance a piglin will accept it and a 50% chance they will want to kill you. There could also be a new mob called the dumb piglin who gives you good barters for fool's gold and if they are attacked from afar then it will attack the nearest piglin. You can make fool's armor and piglin brutes won't attack you until a piglin or piglin brute is attacked.
