Piglin Royal Knight Changes

• Piglin Royal Knights will now correctly attack mobs that attack their owner
• Can now be fed Golden Apples, granting them Absorption 1 for 2 minutes and Regeneration 2 for 10 seconds, as well as healing them for 8 health.
• Now has a 4th behavior mode: Guarding. While in this mode it will:
  • Randomely wander around in a 20 block radius
  • If they are outside of this radius and are not currently targeting a mob, they will attempt to pathfind back to where they were set to guard
  • Attack any monster entities on sight, unless it is below 20% health
  • Defend its owner if they are attacked
• Piglin Royal Knights can be tamed in creative mode by using a gold block on them
  • This was in the previous version, I just forgot to mention it
