Remove handler for Security.certificateError

DevTools has deprecated the old flow of setting overrideCertificateErrors
and then handling an event notification. Instead they are just ignored
upfront.

This was kind-of applied in https://gitlab.com/behat-chrome/chrome-mink-driver/-/commit/457160a51d4792657efe909e8ffa085771f0fa75
so these events will no longer be arriving, and allowing for the possibility
of them just gives yet another place we're tracking page state change and
potentially recursively sending commands.
