Bug 499291

SUMMARY
Running `dnf install kdenlive -y` on Fedora 41 left me with non-functional kdenlive. A few dependencies failed to be installed. I was getting these errors when trying to run kdenlive:

```
$ kdenlive
kdenlive: error while loading shared libraries: libQt6Multimedia.so.6: cannot open shared object file: No such file or directory
$ kdenlive
kdenlive: error while loading shared libraries: libQt6NetworkAuth.so.6: cannot open shared object file: No such file or directory
```

I solved that by manually installing package qt6-qtmultimedia and then qt6-qtnetworkauth.

STEPS TO REPRODUCE
1. Run `dnf install kdenlive -y` on Fedora 41
2. Trying to start Kdenlive from GNOME desktop environment - nothing happens
3. Trying to start kdenlive in a terminal leads to errors

OBSERVED RESULT
First error was "kdenlive: error while loading shared libraries: libQt6Multimedia.so.6: cannot open shared object file: No such file or directory". I fixed it by installing qt6-qtmultimedia. Then another error was "kdenlive: error while loading shared libraries: libQt6NetworkAuth.so.6: cannot open shared object file: No such file or directory". I fixed that by installing qt6-qtnetworkauth.

EXPECTED RESULT
The qt6-qtmultimedia and qt6-qtnetworkauth packages are installed as dependencies of kdenlive.
