@MakisH i checked this quickly , the parser does read the " description" key in BuildArguments.from_components_yaml(), and if it is missing it falls back to No description provided for <argument_name> , So I think this typo does not affect the actual systemtest runs, since the argument names and defaults are still parsed. But we do lose the intended description metadata, so this cleanup still makes sense to me.

Thanks! Then I am merging this, we can revisit the "what to actually do with this" later.
