Validation attributes

[jacobdekeizer]

Summary

Thanks for making this package. I wanted to add custom attributes to the Laravel validator so I can translate the attribute names for the mutation arguments, but this is currently not possible. This pull request will add the custom attributes to the Laravel validator in the GraphQL Field class.

Laravel documentation: https://laravel.com/docs/9.x/validation#customizing-the-validation-attributes

Don't know if you consider adding a new public method as a breaking change or not. Let me know if you have any questions!

LGTM, very nice first PR!

Can you please rebase against master? Couple of months passed and it would be great to ensure everything is working as expected.

Thanks!

@jacobdekeizer thanks! there are a couple of phpstan errors reported, can you check them?

Note: you need to run phpstan with PHP 8.1 (I do this with the included Makefile/Docker stuff). Ping if you've troubles with that.
