Add a command to skip to a new playlist

### Description
I would love to have a command that allows skipping the current song queue to another playlist.
Currently in my server the bot runs playlists that I created locally and even though I can just run ``?remove all ?play playlist `` it just feels clunky and I would love a command that just does both of them (such as ?skip playlist or ?playskip playlist )

Start by locating the existing ?remove and ?play command handlers and trace how they clear the current queue and start a named playlist. The work is done when one new command performs both actions for a locally created playlist, with behavior matching the requested usage such as ?skip playlist .
