Clovers

I was skeptical about this at first, but i feel like it's worth a shot, clovers would be a perfect fit for making the luck potion, and i feel like since we've been getting plenty of loot based items in 1.20, thus, maybe we could get an easier way of getting them?
Clover fields would be generated in a similiar way as the cherry groves (basically a meadow filled with clovers instead of flowers), on which a rare clover varient could generate, this varient is the "four leafed clover", which could maybe be used on brewing the luck potion.

Tell me if there's anything i should add ;P
