Unused sound event: minecraft:entity.zombie.attack_iron_door

The bug

This sound event is completely unused in normal gameplay and can only be accessed via commands. Either it should become used in normal gameplay in some form, or removed from the game entirely alongside its assets (since anyone willing to use it can just add it back in as a custom sound event via a resource pack anyway).

How to reproduce
