Hostile zombified piglins can drop experience orbs even when doMobLoot is set to false

The bug

Killing an zombie piglin in survival during their hostile state causes them to drop xp even when the doMobLoot gamerule is set to false.

To reproduce

1. disable doMobLoot
2. Spawn a zombified piglin
3. Go to survival and kill the zombified piglin
   → They're dropping experience even if doMobLoot is set to false
