docs: Bans a user from using the bot.
  
          This bans a person from using the bot in the current server.
          There is no concept of a global ban. This ban can be bypassed
          by having the Manage Server permission.
  
          To use this command you must have the Manage Server permission
          or have a Bot Admin role.
