Not sure why this keeps failing with npm error 401 Unauthorized - GET https://npm.pkg.github.com/download/@camunda/zeebe-element-templates-json-schema/0.22.1/e9731bb7d19ec7a4212f0c09982d2d1f9570bb19 - authentication token not provided but it's also odd that https://www.npmjs.com/package/@camunda/zeebe-element-templates-json-schema?activeTab=versions still doesn't show v0.22.1.
