    Adapt metadata key name
    
    GeditDocument now uses TeplFileMetadata.
    
    For the bookmarks, unfortunately there is a bug, the bookmarks metadata
    don't work, quitting gedit and re-loading the file doesn't bring back
    the bookmarks. The bug is not a recent regression with TeplFileMetadata,
    the bug also occurs with gedit 3.32.
