    content: fix "revision" value in the json file.
    
    GIMP's code expects it to be int. I am going to also improve GIMP code
    to detect string and convert it to int, because this data error may
    happen again.
    Anyway still fixing the json file so that update detection work
    appropriately on existing builds.
