Registers slash commands for your Discord bot, globally or in one guild. Note that this overwrites old commands.
app_id: Your bot's application ID as a string
guild_id: Provide a guild ID as a string to apply the commands only in one guild, or use null to apply globally. Note that applying commands globally takes a while on Discord's end.
token: Your bot's token.
commands: An array of command objects to register. For a basic command with no arguments, only name and description are needed.
