fix: Laravel 10 support

[riiad]

This PR ensures compatibility with Laravel 10 by replacing calls to Config::arr and Config::string with the config helper.

fixes #57 (comment)

Let me know if you’d like me to add more details! 🚀

@riiad - I just added the same thing! Haha (#65)

The only extra bit I added was a method to ensure if the developer changes the types returned by the config when published it gracefully throws an exception:

Maybe you could add this in & I will close my PR?

    private function checkType(mixed $value, string $type): void
    {
        $actualType = gettype($value);
        if ($actualType !== $type) {
            throw new InvalidArgumentException("Config value must be of type {$type}, {$actualType} given.");
        }
    }

@CamKem Right, i added a method to check the type.
