The Bug:

Sniffer egg sound events are listed under "entity" instead of "block".

Sniffer eggs are blocks, not entities, therefore their sound events should be listed under "block" instead of "entity".

Steps to Reproduce:

1. Enter the following command in chat without sending it.

   /playsound minecraft:entity.sniffer.egg

2. Hit the TAB key.
3. Take note as to whether or not sniffer egg sound events are listed under "entity" instead of "block".

Observed Behavior:

Sniffer egg sound events are listed under "entity".

Expected Behavior:

Sniffer egg sound events would be listed under "block".
