🚀 Dynamic Voice Channel Exit for Enhanced Bot Efficiency

[Eric-Schubert]

Is your feature request related to a problem? Please describe.
It is inefficient when the music bot remains in the voice channel even after it becomes empty, unnecessarily using resources.

Describe the solution you'd like
I would like the bot to automatically leave the voice channel if no users have joined it within the duration specified by the STAY_TIME (e.g., 30 seconds). The bot should disconnect if it finds itself alone in the channel after this interval.

Describe alternatives you've considered
Currently, there is no mechanism in place to dynamically manage the bot's presence in voice channels based on user activity. The proposed solution introduces this needed functionality for the first time, enhancing efficiency and resource management.

Additional context
This feature would be useful on large servers where channel activity frequently changes, ensuring the bot is active only when needed and conserves resources by not lingering in inactive channels.
