    Link to gtkmm 3.22 and glibmm 2.50
    
    In preparation for future releases that will be compatible with the
    ABI-breaking gtkmm-4.0 and glibmm-2.52, let the links from the generated
    html files point to gtkmm 3.22 and glibmm 2.50 instead of the usual latest
    unstable documentation and git's master branch. Bug 773642 comment 4.
