Doc: Qt Network: Fix references to renamed functions

As part of the API review process, in QNetworkRequestFactory:

(set|clear)Headers() were renamed to (set|clear)CommonHeaders(), and
request() was renamed to createRequest().

In addition, QHttpHeaders::has() was renamed to contains().

Update references to the old names in the documentation.

Pick-to: 6.7
