Summary:
Baby zombie villager curing sound (minecraft:entity.zombie_villager.cure) and conversion sound (minecraft:entity.zombie_villager.converted) aren't higher pitched.
Baby piglins sounds of conversion are higher pitched, so I expected that the rest of the sounds of the baby mobs would sound higher MC-172434.

Steps to reproduce:

1. Summon a baby zombie villager that is about to convert into a villager by using the command provided below.

   /summon minecraft:zombie_villager ~ ~ ~ {IsBaby:1b,ConversionTime:30}

2. Observe how the conversion sound isn't higher pitched.
3. Obtain a golden apple and summon a baby zombie villager that has the weakness effect by using the command provided below.

   /summon minecraft:zombie_villager ~ ~ ~ {IsBaby:1b,active_effects:[{duration:-1,amplifier:0b,id:"minecraft:weakness"}]}

4. Observe how the curing sound isn't higher pitched.

Observed results:
Baby zombie villager curing sound and conversion sound aren't higher pitched.

Expected results:
Baby zombie villager curing sound and conversion sound are higher pitched.
