Vocab improvements

I had to dig into this repository to figure out how to control the volume except one unit at a time. Here are things I tried before I looked up the right words:

• Set volume to max
• Max volume
• Increase volume to max
• Increase volume all the way

Some other things that might be good to cover:

• Turn the volume down
• Turn the volume up

Hey there, these phrases should all now work with the Volume Skill.

Thanks for the great feedback (and apologies for the very slow response)
