Filter out [dev] comments earlier

Previously we only filtered them out from the example config section in
Config.md, but they still appeared in the schema. This is not ideal, because the
schema descriptions can appear in editors on mouse hover or in auto-completions.
So filter them out earlier, so that they don't appear in the schema either.
