Summary:
Warden does not have an animation for taking damage. In the Java version, he staggers when taking damage, while in Bedrock he does not move at all when taking damage.

Steps to reproduce:

1. Summon a Warden.
2. Hit him (or damage him in any way).

Observed results:
Warden didn't react to the damage in any way (apart from the sound of the damage and reddening of the textures).

Expected results:
When taking damage, Warden will have a damage animation.
