Rebalance Netherrite Weapons (to keep axe a bit useful)

1.16 makes axes more useless for PvE Combat than they already are.

Axes do not get Sharpness, Bane of Anthropods or Smite on the Enchanting Table, it is notoriously hard to get an axe that is of any use for combat. But before 1.16 you got a decent reward for grinding for that Smite V book:
‣ A Smite V Axe was the only weapon that could one-hit-kill a Zombie Pigman without critical hit.
It was a small benefit, that many people didn't even know about, but it was an incredibly useful single usecase where the axe was good for combat.

With 1.16, a Smite V Netherite Sword can do that too. Additionally it outclasses the Trident in meele even more.
Now there really is no reason anymore for doing close combat with anything else than a sword... besides maybe in the first day when you might use some stone axe.

Please give the axe some use back.
You could in example:
‣ Increase the armor of Zombified Piglin from 2 to 4 (would make them one-hit-kill by Smite V axe only again)

(in my opinion, being able to sprint through the nether with no status effects and one-hit killing every single zombified piglin in sight without crit and without them getting angry is overpowered and should be for a slow axe only - the ordinary player would prefer a strength potion to the hassle of getting a Smite V book anyway)
