Can't find 'action.yml', 'action.yaml' or 'Dockerfile' under '/home/runner/work/step-interview-sample-app/step-interview-sample-app/.github/workflows/action.yml'. Did you forget to run actions/checkout before running your local action?

The following actions uses node12 which is deprecated and will be forced to run on node16: actions/checkout@v2. For more info: https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/
