feat: integrate music commands with Lavalink support

- Added new music commands: play, queue, and volume. - Implemented music management using disgolink for Lavalink integration. - Updated bot initialization to include Lavalink host and password. - Enhanced interaction handling for music commands, requiring DJ role for usage. - Introduced now playing message with interactive buttons for controlling playback. - Updated dependencies in go.mod for disgolink and snowflake.
