Hydrogen now support extensions of type
org.freedesktop.LinuxAudio.Plugins. Currently they depend on
freedesktop 22.08 (which the KDE 5.15-22.08 runtime depend on).
So careful consideration should be to update the runtime as this will remove the extensions that the user might have installed and expect.
Sadly the appstream file checks must be skipped due to improper metadata license, which an issue has been fixed upstream for.
Use git source otherwise the build will be marked as development.
