No empty sound event for the pale garden overworld music

How to reproduce:

Ensure you have access to commands.

• Verify that there is a sound event for the warped forest using this command in chat:

/playsound minecraft:music.nether.warped_forest

• Verify that there is not a sound event using the command below (intentionally incomplete) in chat:

/playsound minecraft:music.overworld

Expected Results:

For consistency with the warped forest (which also does not play music), there should be an empty sound event for the pale garden.

Observed results:

There is no sound event available (even an empty event) for the pale garden biome
