Updated the README to provide clearer descriptions for the `gcp-bucket-crossplane-health` and `stg-workspace-smoke` code bundles. The `gcp-bucket-crossplane-health` now specifies its focus on Kubernetes platform and k8s-kubectl-cmd runtime, while the `stg-workspace-smoke` is noted for its integration of runwhen and tool-builder runtime. This improves documentation clarity for users regarding the purpose and structure of these bundles.
