Apply Laravel coding style

Shift automatically applies the Laravel coding style - which uses the PSR-12 coding style as a base with some minor additions.

You may customize the code style applied by configuring [Pint](https://laravel.com/docs/pint), [PHP CS Fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer), or [PHP CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer) for your project root.

For more information on customizing the code style applied by Shift, [watch this short video](https://laravelshift.com/videos/shift-code-style).
