Plasma Discover is currently downloading older versions of native Fedora packages instead of the latest ones available in the repositories. After installation, Discover immediately prompts the user that an update is available for the package that was just installed.

Reproducible: Always

Steps to Reproduce:
1. Install Fedora 44 with KDE Plasma
2. Update the System and Reboot
3. Go to Install a Package with Plasma Discover
4. Check the Updates tab on Discover
Actual Results:
Discover lists and installs an outdated version of the native (RPM) package. Upon successful installation, Discover immediately prompts that there are updates available to said package.

Expected Results:
Discover should read the repository metadata correctly and directly install the latest available version in the Fedora 44 repositories on the first try.

Additional Information:
DNF behaves correctly: If you bypass Discover and use the terminal (sudo dnf install kdenlive), DNF correctly finds and installs the latest version right out of the gate.

Flatpaks behave correctly: Installing Flatpaks directly through Discover (whether using the Fedora Flatpaks remote or Flathub) works perfectly and pulls the correct, latest versions.

Possible Cause: Because standard dnf and Flatpaks work flawlessly, the issue is strictly isolated to Discover/PackageKit. Since Fedora 44 recently transitioned PackageKit to the new DNF5 backend, this bug is highly likely related to how the new PackageKit DNF5 integration reads or caches native RPM repository metadata.
