Missing knockback delay for the ravagers

Ravagers have a missing knockback delay as you keep hitting them this bug wasn't fixed until i found out that they have a missing knockback delay on them its been a bug since release 1.16.0 - 1.16.210.58 the bug also happens on Java Edition

Steps to reproduce

1. Go back to release 1.14/1.11 (any 1.14/1.11 versions)
2. Create a new world (Any world type)
3. Grab a ravager spawn egg
4. Spawn them anywhere you want
5. Grab any weapons (you can also use your fist)
6. Keep hitting the ravager, as you hit the ravager you will actually notice that on some hits, the ravager doesn't take knockback then a couple more hits they do take knockback because they used to have a knockback delay

     7. if you saw the ravager wont take knockback on some hits then 

        It does thats the knockback delay

     8. Now after observing the knockback delay go back to 1.16

         (Any versions) once again grab a ravager spawn egg

     9. Grab swords or use your own fist

     10. The bug should now be visible you should notice that the ravager

           Takes knockback more often and theres no longer a knockback

           delay.

 

   Observed results:

   Ravagers have knockback delays that on some hits they will not take

   Knockback then it will take knockback if you add more hits

 

   Expected results:

After the release of 1.16.0 knockback delay for the ravager is gone and as you hit them they just constantly take 50% knockback instead of having knockback delays just like on 1.11 - 1.14 versions.
