For example:

  Commands:

    preview         [file] [args...]      - Render and preview a document or website project.

    help            [command]             - Show this help or the help of a sub-command.
```

That is, invoking `quarto` (without arguments) just silently does nothing. Should it instead print help by default, or something similar?
