Unfortunately there are a few job parameters that have default values that differ when no value is specified vs an empty value is specified. For example: `rules` and `needs` behave differently if not specified at all vs an empty array `[]`. The yaml file format suggests that a `null` might be want we wan to "unset" the value, but this does not work to clear Component inputs. See: https://gitlab.com/gitlab-org/gitlab/-/issues/439524.
