    Add missing gimp-image-grid help id
    
    The GIMP help id for configuring the grid is gimp-image-grid, so adding
    that id to the documentation.
    
    I choose not to remove the id's that include configure, since I think that
    is a more descriptive name, that we maybe should use in GIMP too.
