Description Ben Nham 2023-04-12 14:09:51 PDT

Newer versions of CFNetwork use `didReceiveInformationalResponse:` instead of `_didReceiveInformationalResponse:` as the delegate callback for returning 1xx responses such as 103 Early Hints. We need to update WebKit to use the appropriate delegate method based on the version of CFNetwork being used.
