✨ added validation customAttributes

[fabianmieller]

Laravel allows the use of customAttributes for validation messages.

With my pr, I added the ability to add a "customAttribute" to the option.

$this->option('contact.email', 'required|email', [], 'E-Mail-Address')->verify();

Response without customAttributes

{
    "status": "error",
    "errors": [
        {
            "status": 400,
            "message": "contact.email",
            "detail": "Contact.email ist ein Pflichtfeld."
        }
    ]
}

Response without customAttributes

{
    "status": "error",
    "errors": [
        {
            "status": 400,
            "message": "contact.email",
            "detail": "E-Mail-Adresse ist ein Pflichtfeld."
        }
    ]
}
