Redirects to a short-lived signed URL for an artifact persisted by Runway from the newest non-skipped build on a Flightpaths release-candidate step. Omit `artifactId` to select the preferred primary binary artifact, or pass an artifact ID from the newest build returned by the existing release-step endpoint. This works for every CI provider when Runway has persisted the artifact.
