    buildworker,buildmaster: bump Debian to version 12
    
    Debian 11 LTS support ends in June 2026, so it's probably around the
    time when support for the OpenWrt 24.10 release might end. Therefore,
    let's switch to Debian 12, which should have LTS support until June 2028
    and is the latest and greatest.
