When a navigation is upgraded to https as a result of upgradeKnownHostsToHTTPS being enabled, the embedder does not get any navigation callback for this implicit redirect. While these upgrades are not actually server redirects, the existing didReceiveServerRedirectForProvisionalNavigation seems like the most straightforward way to notify an embedder, without having to introduce new public API in WKNavigationDelegate. Without any callback, embedders only see an unexplained URL change, and it seems fragile to assume this is a redirect of an existing navigation.
