Don't validate empty (null) value just return false

[Shonetow]

I noticed an issue when trying to submit a form without checking the hCaptcha button. It gave me this error:

Panfu\Laravel\HCaptcha\HCaptcha::validate(): Argument #1 ($token) must be of type string, null given

To fix it, I added a ternary operator that checks if the value is empty and returns false if it is.

Let me know what you think!

Glad you noticed and thanks for your pull request!

However, I would adjust the validate function instead and make $token nullable by putting a question mark in front of it. The function itself already checks if the value is empty and then returns false.

If you can just change that, I can merge your pull request.

Of course, it makes more sense now that I've actually looked at the validate function. 😁

Perfect, I've merged it and am getting a version ready for Packagist.
