Add a way to change sec-ch-ua client hint

Currently there are many user agent client hints that can be adjusted as of Qt 6.8. However, it seems I can't change the main sec-ch-ua header which still sends the old user agent and brand even after changing the user agent and user agent hints using the client hints. I would like an addition to the client hints to add the sec-ch-ua option or to infer it from the other options (such as fullVersionList or fullVersion string). If there is already a way to do this and I'm just ignorant of it please let me know.
