1.21.1 issues for CmdAttribute - list/remove

[BlaneyXYZ]

In 1.21.1 AttributeModifiers now use NamespacedKey rather than UUID.

Currently the method to add a modifier is

AttributeModifier(UUID uuid, String name, double amount, AttributeModifier.Operation operation, EquipmentSlot slot)

The new method is

AttributeModifier(NamespacedKey key, double amount, AttributeModifier.Operation operation, EquipmentSlotGroup slot)

This means we can add a modifier but then have no reference of what it actually is because getName() will now return the NamespacedKey

I have attached a screenshot of /attribute list between 1.21 and 1.21.1
