Issue Description: The CI job failed during the "Cluster Authentication" step because the Kubernetes configuration file was not found.

Failure Details: The build log shows a fatal error: `Error: kubeconfig file not found at /tmp/secret/kubeconfig`.

Root Cause Analysis: The CI process is unable to proceed with authenticating to the Kubernetes cluster because the required `kubeconfig` file is missing from the expected directory (`/tmp/secret/`). This points to an issue with the CI environment setup, where the secret containing the cluster credentials was not correctly mounted or made available to the build pod.

Actionable Recommendations:
1. Verify the CI job's configuration in Prow/Tekton to ensure the secret containing the `kubeconfig` is correctly defined and mounted into the container at the `/tmp/secret/` path.
2. Check the health of the secret management system (e.g., Mapt) to confirm that the secret is available and accessible to the CI job.
