Missing sounds when a hostile mob shoots arrows or throws trident

When a skeleton shoots or a drowned throws the trident you cannot hear the sound.

You can reproduce it by following the steps:

1. Create world in creative mode.
2. Summon a skeleton or drowned.
3. Go into survival mode and you can only hear the arrow or the trident's hitting sound when land into the ground or the player but there is no shooting/throwing sund.

There is a fix for that: This bug caused by no sound definitions for these in the sounds.json in the vanilla resourcepack.

1.  You need a sound definition to the skeleton shoot sound by putting a "shoot": "random.bow"
2. You need a sound definition to the drowned shoot sound by putting a "shoot": "item.trident.throw"
