Old vibe sound button is still there

[KatieWoe]

Test device: Dell Operating System: Win 10 Browser: chrome Problem description: For https://github.com/phetsims/QA/issues/338 and https://github.com/phetsims/QA/issues/341 During this rc, sound in the game was switched from vibe to tambo. This means that muting is controlled by the nav bar button. However, the old yellow sound button is still present in the game screen. It does not seem to do anything, and the nav bar button seems to work from what I've seen so far. Steps to reproduce:

1. Go to a game screen
2. Play the levels with various combinations of muting.

Assigning @jbphet as well in case there is some trouble switching over.

Good observation @KatieWoe. This should go to @jonathanolson, since he did the conversion for this sim.

Somehow I missed a commit in the cherry-picks. I'll make sure this is included in the next RC.

Looks good in the rc's
