Baby piglin drops 1 XP when killed, instead of 5 XPs like baby piglin in Java Edition and adult piglin

Description:
In Java Edition, baby piglin drop 5 XPs consistent with adult piglin when killed. However, in Bedrock Edition, baby piglin only drops 1 XP when killed, which is different with adult piglin and breaks parity with Java Edition.

Steps to Reproduce:

1. Spawn a adult piglin and a baby piglin
2. If XP level is not empty, use /xp command to remove all XP levels
3. Kill the adult piglin and pick up XPs dropping from it
4. Observe XP bar and remember its length
5. Use /xp command to remove all XP levels (again)
6. Kill the baby piglin and pick up XPs dropping from it
7. Observe XP bar and compare with the length of XP bar atfer picking up XPs dropping from adult piglin

Observed Results:
Can find that their lengths are different, which means that adult piglin and baby piglin drop different XPs.

Expected Results:
Their lengths should be same.
