This commit changes the default return value of `Auth::ManagedAuthenticator#primary_email_verified?` to false. We're changing the default to force developers to think about email verification when building a new authentication method. All existing authenticators (in core and official plugins) have been updated to explicitly define the `primary_email_verified?` method in their subclass of `Auth::ManagedAuthenticator` (example commit https://github.com/discourse/discourse/commit/65f57a4d05496d05a4de9a6a641ec760c7004c7a). Internal topic: t/82084.
