Additional Context

From Spigot JavaDoc's:
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/CreatureSpawnEvent.SpawnReason.html#PIGLIN_ZOMBIFIED

"When a piglin is converted to a zombified piglib."

(piglib there is a typo, interesting. don't have spigotmc stash access and lazy to get access/pr a small change like that but someone reading this can, maybe?)
