Handle playlist links with specific song selected

If a link contains both a video and a playlist, it will now only add the specific video, not the whole playlist.

This looks like it will make it difficult to add a playlist to the queue

[themadprofessor]

Playlists can still be added. https://www.youtube.com/playlist?list=... will queue the playlist, whereas https://www.youtube.com/watch?v=...&list=... will queue just the video. This could be put behind a config variable, keeping the existing method if its false.

The current behavior is deliberate

An acceptable solution would instead be to ask the user if they prefer one track or all tracks when using such a URL. This could ideally be done with buttons https://discord.com/developers/docs/interactions/message-components
