ng-recaptcha often returns a token in offline mode

[hemmoleg]

Hello,

I wanted to test my error handling for the recaptcha service. What I found during testing is that most of the time the service returns a token when run in offline mode.
This issue also includes the demo provided at the "see in action" links. In the doc says you should just go to the site and set your browser to offline mode to see how the error handling works. However, most of the time you wont get an error and instead will get a legitimate token. To test this, just open the link https://dethariel.github.io/ng-recaptcha/v3 set you browser to offline and click any of the buttons. You will see that only occasionally you will get an error.

It does look like reCAPTCHA v3 can now function in offline mode as well. I'm afraid there's little I can do since the lib doesn't have control over reCAPTCHA internals.
