The Bug:

Pillagers don't raise their arms upon winning raids.

Evokers and vindicators raise their arms upon winning raids so one would expect the same behavior for pillagers.

Steps to Reproduce:

1. Place down a bed and summon a villager next to it.
2. Give yourself the bad omen effect to start a raid by using the command provided below.

   /effect give @s minecraft:bad_omen

3. Allow the raiders to kill the villager so that they win the raid.
4. Watch the pillagers within the raid closely as they celebrate.
5. Take note as to whether or not pillagers raise their arms upon winning raids.

Observed Behavior:

Pillagers don't raise their arms upon winning raids.

Expected Behavior:

Pillagers would raise their arms upon winning raids, just like how evokers and vindicators do.
