Is your feature request related to a problem? Please describe.
I'd like to be able to use hotkeys to raise or lower the volume of a media_player entity in HA. Play / Pause works great via "toggle".

Describe the solution you'd like
Add QuickAction for action: media_player.volume_up and action: media_player.volume_down

Even better (if possible) would be to allow service calls from QuickActions. That would be very flexible.

Describe alternatives you've considered
Create a script that raises volume, and a script that lowers volume
