[1.20.1] Wrong audio when using keybind spells

[ChrisJacobs2]

Hello.

I found a minor bug when I changed my digging spell to use the gaia sounds.

Other spell slots will use the default sound, which is normal. However, when I have the digging spell selected, and use a spell keybind, such as slot 4, bound to mouse 4, I notice that it makes the gaia sound, even though the spell in slot 4 uses the default sound.
