Some C418 music have duplicate files

In the latest preview, some C418 music with their official titles has been added to the game (such as sweden.ogg, wet_hands.ogg, subwoofer_lullaby.ogg, etc.), but their previous files that uses generic name (such as calm3.ogg, piano2.ogg, hal1.ogg, etc.) is still present.

Since Java Edition 1.20.3 rename all of the C418 music from generic name to their official titles, the files that still use generic name should be removed entirely.

• hal1.ogg (subwoofer_lullaby.ogg)
