Add clickable Link prompt

[luanfreitasdev]

Sometimes we want to show a clickable link to the user, so this PR adds the "link" functionality, which is supported by most current terminals on Linux and macOS.

link(
    message: 'Visit Laravel documentation:',
    path: 'https://laravel.com/docs',
    tooltip: 'Click here'
);

IMO this seems out of scope for this project.
