addcookie doesn't work with 90.0.818.46

[popyoung]

After I updated from 89 to 90, the original code throws an exception.

OpenQA.Selenium.InvalidCookieDomainException:“invalid cookie domain: Cookie 'domain' mismatch
(Session info: MicrosoftEdge=90.0.818.46)”

[popyoung]

The reason has been found, because of restrictions SameSite. I loaded the cookie without first navigating the corresponding domain name. It may be that SameSite has been restricted after 90 version, or the website I visited has strengthened restrictions, but it happened that I upgraded the 90 version.

@popyoung this is a known issue with the WebDriver spec. For details see w3c/webdriver#1238

I'm going to close this issue since this repo is now deprecated.
