this is likely because an older npm version is being used in that pipeline. for auditing signatures, the latest npm version is needed. we've added the packageManager property the package.json of others of the repos under this org using corepack: corepack use npm@latest. with that added, we can prepend the audit command as corepack npm audit signatures and it will make sure to leverage the npm version from the packageManager property. renovate will also keep that value from growing stale for us
