Soul Sand and Soul Soil have no sounds

Confirmed for 20w07a.

For some reason, the sound events for soul sand and soul soil got renamed to use _ instead of . (as seen on burger). For instance, block.soul_sand.break was changed to block.soul_sand_break. All other blocks were left unchanged (burger). The names for those events in sounds.json were not changed, although sounds.json was updated between the assets index last week and this week's. It used to be this, and now is this; although it was updated, that was only to add piglin and hoglin sounds and the snow golem shear sound (MC-94094).

I don't know why they renamed the sound events for soul sand and soul soil; it doesn't seem like a logical change and probably should just be reverted to fix this issue.

Would be better if they fixed the sound files themselves, it's best if the sound event names are correct.

Still present in 20w08a; the names for soul sand and soul soil still use an _ for the second split while all other events still use a ..

I made a temporary fix for this. I attached it to the post, but accidentally attached it twice. (Since I thought dragging it over would attach it to my own post, and it didn't work so I tried again and then noticed after that it was being put on the main post)
If a moderator could remove one I'd appreciate it.
Basically it's a simple sounds.json fix to make it play the other sound events for now, until Mojang fixes the blocks to use the correct sound events.
