📌 Summary

This PR fixes issue #2859 and updates the Helm chart package to include the correct version of the logical_backup_docker_image, aligning it with the operator version v1.14.0. This ensures consistency across deployments and avoids potential mismatches between the operator and its backup tooling.

• Supports smoother upgrades and version alignment

🧪 Validation

• Confirmed that the .tgz archive was properly updated and committed
