CloudPirates Open Source Helm Charts: GitHub Actions workflow leaks PAT and SSH signing key via unsafe credential handling

CloudPirates Open Source Helm Charts is a collection of Helm charts. Prior to commit fcf9302, a GitHub Actions workflow (generate-schema.yaml) exposes sensitive credentials (Personal Access Token and SSH signing key) to fork-controlled code due to unsafe checkout and credential handling practices. This issue has been patched via commit fcf9302.
