[gnome-boxes/recommended-downloads-always-look-for-latest-version-in-osinfo-db: 2/5] recommended-downloads: Fallback to OSinfo.Os.id prefix when Os is not found

    recommended-downloads: Fallback to OSinfo.Os.id prefix when Os is not found
    
    If the exact Osinfo.Os.id isn't found in the Osinfo database, we
    search for the latest version that matches the prefix of the OS id.
    
    This allows the recommended-downloads list to contain incomplete
    Osinfo.Os IDs, solving our issue with hardcoded version numbers.
