Currently marge only ignores `error_type` when the type is None. But other error_types are equally uninteresting e.g. `error_type: Jobs`. Example: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32677#note_2711470 https://gitlab.freedesktop.org/mesa/mesa/-/pipelines/1333563 Ignore the phrase `error_type` so marge will provide more useful comments.
