Slash Command - p!mute (misc.py)

[alfadelta10010]

Create a slash command for the mute command.
Also ensure that the command shows up in discord's slash command menu.
You are free to update the discord-py-slash-command library from 3.0.3, provided you explain why.

Here is what is expected of the mute command:
Upon muting a person, they must be assigned a specific role. It is highly advised to make the role value a variable and mention it above in the program, so that the actual role value can be changed easily.
