Hi

I've got two more mingw-qt6-* packages which are up for review, both are 
straight forward mingw/c++ packages.

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=2009269 - 
mingw-qt6-qtwebchannel
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=2070708 - 
mingw-qt6-qttranslations

Happy to review in exchange

Thanks
Sandro
