    app, docs: fix GIMP's version in --dump-gimprc-manpage and update…
    
    … gimprc's manpage as a consequence.
    
    When running `gimp-console-2.99 --dump-gimprc-manpage` to output a man,
    a line was:
    
    > .TH GIMPRC 5 "Version @GIMP_VERSION@" "GIMP Manual Pages"
    
    This is clearly the autotools substitution syntax, which is not being
    used here (this is not a .in file processed by the build system), maybe
    from some older build logics.
