Bounce and Flurry music discs have unused, un-deprecated music disc description translation keys

The bug

With the introduction of data-driven jukebox songs, the old music disc translation keys of the form (item.minecraft.<id>.desc) were deprecated, and added to deprecated.json, making them no longer work.

When Tears and Lava Chicken were later added, they were incorrectly given duplicate translation keys of the old kind, and these were later deprecated as well in 25w36a.

Now Bounce and Flurry have been added, and they too were incorrectly given duplicate translation keys of the old kind. These keys have not yet been deprecated, so still work:

• item.minecraft.music_disc_bounce.desc

• item.minecraft.music_disc_flurry.desc

How to reproduce

1. /tellraw @a {translate:"item.minecraft.music_disc_wait.desc"}

2. /tellraw @a {translate:"item.minecraft.music_disc_bounce.desc"}

Expected result

Both commands should output the literal text provided

Observed result

The second command outputs “fingerspit - Bounce” because that key is not deprecated, despite being unused
