    app: make update detection more robust to string revision field.
    
    The "revision" field in the json file is supposed to be int. But I just
    realized that it was set as string a few times, e.g. in Windows
    installer revision 1 of GIMP 2.10.32. As a consequence, the revision 0
    build was not able to detect the new revision.
    
    I have now fixed the data in gimp-web repo (commit e7690e36), yet just
    in case this ever happens again, I make the parsing code more robust by
    accepting string revision, then properly converted to int.
