Updating the app.php documentation for the latest Laravel

[Alexandre1BR]

'providers' => [ PragmaRX\ZipCode\Vendor\Laravel\ServiceProvider::class, ]

'aliases' => [ 'ZipCode' => PragmaRX\ZipCode\Vendor\Laravel\Facade::class, ]

Let me try to understand: is this missing in the docs? For the latest Laravel that should not even be necessary, we now have the artisan package:discover command, which is supposed to boot those things (service provider and aliases) automatically.

I think we may need a PR to fix all those stuff. :)
