Wither skeletons don't automatically attack piglins and piglin brutes

Repost of MC-172567 for the bedrock edition.

the piglins and piglin brutes attack the wither skeletons on sight, but the wither skeletons don't attack them on sight, they wait to be attacked.

To reproduce

1. Spawn a piglin or a piglin brute

2. Spawn a wither skeleton
   → ❌ Even if they are historic enemies with the piglins, the wither skeleton does not attack the piglin on sight while the piglin or piglin brute itself is attacking the wither skeleton on sight.
