The Bug:

The block ID of note blocks is "note_block" but this is presented as "noteblock" within the NBT data of allays.

Having the word "note block" inconsistently spelled throughout several areas of the game creates an inconvenience for the player and misleads them as the correct usage is not immediately apparent. The spelling of this word should match its block ID for ease of convenience. Please refer to MC-249984 for a similar concept.

Steps to Reproduce:

1. Obtain some items, place down a note block, and summon an allay.
2. Give the allay an item and tune/play the note block.
3. Inspect the allay's NBT data by using the command provided below.

   /data get entity @e[type=minecraft:allay,limit=1,sort=nearest]

4. Look for the names of data that include the word "noteblock".
5. Take note as to whether or not the names of note blocks within allays' NBT data follow the names of their block ID.

Observed Behavior:

The names of note blocks within allays' NBT data don't follow the names of their block ID.

Expected Behavior:

The names of note blocks within allays' NBT data would follow the names of their block ID.
