SkeletonsHurtWither

This mod works a different way than the Fabric one.

With that version, only one wither can be damaged by skeletons at the time.

Firstly, you need to make the wither attack the entity you want, which will set its health to the maximum and set it as the saved entity.

Secondly, make skeletons attack the wither and if the wither dies, another wither can be set.

I was not able to create this forge version for all withers and skeletons, sorry.
