Updated basic_voice.py example for app_commands.

Idea

This can be moved to a different category if "Idea" isn't the proper place. (sorry if I put this in the wrong spot)

A new and updated example for basic_voice in the app_commands examples. I am not expecting this to be done anytime soon but I thought it'd still be very helpful.

---

I have been trying my hand at working with a bot that'd use voice channels, playing music, etc. And the issues I keep running into are trying to translate the old and non preferred method of commands by sending a message in the chat like !play and having the bot respond to that. To the new way with app_commands/slash commands, etc.

The old way uses from discord.ext import commands and ctx. I however can't do that because app_commands & interactions. I thought that maybe someone could make a new and updated example for basic_voice.py but in the app_commands folder/directory.

Also an additional note, I have my bot and client set up in a similar way (if not the exact same way) as the examples in examples/app_commands so trying to work with basic_voice.py is even more of a headache. On top of not using cogs and classes for literally everything.

Extra little rant

Can be ignored and isn't related to the above idea. (better documentation is what this would fall under)

I have also spent more than 24hrs alone just trying to understand the documentation for working with voice stuff but it really doesn't seem to help much. Outside of telling me what something is and what something means...but with no way of how to use it properly or what it'd look like to be used, or literally anything it can do... So telling me to just "read the documentation" or "follow and example" isn't working and hasn't worked. Especially when every search result that I can find outside of the documentation on google or whatever search engine to be used, and on stackoverflow is just the same thing...old and outdated discord.ext commands and ctx stuff. And I can't work with that.
