Wither rose is Common, despite requiring Rare items to obtain

The bug

The wither rose is assigned a Common rarity, despite the fact that it can only be obtained via use of a wither skeleton skull, which is considered to be Rare.

The 24w33a changelog would imply that since a rarer item is required to obtain this, it should inherit that rarity.

How to fix

Increase the wither rose's rarity.
