Update laravel.md

Added additional configuration to the Laravel example nixpacks.toml to work better out of the box. Automatically generating necessary directories, changing permissions, running migrations and running queue. This will make the example environment work for a more broad range of Laravel application and closer reflect how deployments are handled on other popular hosting services.
