QWebEngineClientHints::fullVersionList is not extended as documented

The documentation of QWebEngineClientHints::fullVersionList states that

The provided values will be automatically extended by the currently used version of Chromium and a semi-random brand.

However, I have not witness such behavior: Sec-CH-UA-Full-Version-List is the exact list provided to setFullVersionList().

I am fine with the current behavior, I think the documentation should be modified to suppress this part.
