Feature desciption

By writing a command in the chat (eg: boo!scare/boo!booh/something else), the bot will join you in the voice channel to play a scary sound. Once the sound is played, the bot leave the channel.
It could be fun to have a library with various sounds (around 10) that are played randomly.
Last year library.

Teachability, Documentation, Adoption, Migration Strategy

Before joining a voice channel, the bot need to handle some potential errors:

• Check if the user who sent the command is in a voice channel,
• Check if the bot has the right to join the channel,
• Check if the bot has the right to speak in the channel.

If the bot handle an error listed above, you should display an embed for at least 10 seconds displaying an error message explaining why the bot can't do one thing or another.
You can find embed templates in the other command files.
The newly command need to be stored in a file having the same name as the command string. It should also be stored in the ./commands/Fun/ folder.
