fix: add missing @snazzah/davey (DAVE) and ws dependencies

Jukebox has @snazzah/davey (Discord Audio Video Encryption) and ws
(WebSocket) as dependencies which were missing from the Gaming Hub.
Without davey, voice connections get stuck at 'signalling' because
Discord's voice servers require DAVE negotiation in @discordjs/voice 0.19.
Also removed unused prism-media (covered by @discordjs/opus).
