    devel-docs: fix again
    
    This will work around such errors from the g-ir-doc build:
    
    > devel-docs/g-ir-docs/pages/python/Gimp-3.0/Gimp.checks_get_colors.page:46: parser error : EntityRef: 
expecting ';'
    > gimp_checks_get_colors (gimp_check_type (), &color1, &color2);
    >                                                    ^
    
    Similar to commit 7123b6c466, it cannot really be considered a proper
    fix, barely a workaround for g-ir-doc-tool not even able to produce
    valid XML. Here we have ampersands which it should have espaced into XML
    entities.
    Anyway this will do for now (until we just decide to drop the g-ir-docs
    tools?).
