Show help for unknown command

[Amnish04]

I noticed that when a user enters an invalid command, we get the following toast message.

I found a TODO while working on another issue that we need to handle this as appropriate for the application.

The regular /help command shows a generic list of in guidelines for the app.

Should we rather only show the commands supported by ChatCraft when this happens?

Which would be this section:

Sure, it makes sense to show a list of commands.
