ci: pipeline_message: parse fatal messages

Currently marge only parses a failed job log for error messages, which can
cause her to miss fatal messages.

Example:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32557#note_2696196
https://gitlab.freedesktop.org/mesa/mesa/-/pipelines/1327177

If a `fatal` message is in the error log, add it to the pipeline message.
