The Lunge enchantment now works at 6 hunger and above, instead of 7

The Lunge enchantment can now be used when the player is at 6 hunger points (3 food icons); this is inconsistent with 1.21.11, which required at least 7 points (3.5 icons).

Reason: In the latest snapshot, the “post_piercing_attack” enchantment trigger now requires a predicate to prevent use below 7 hunger, instead of being hardcoded that way. The predicate that was applied to the vanilla Lunge enchantment specifies a minimum food level of 6, when it should be 7.
