Kubernetes attributes promoted to release candidate in OTel Semantic Conventions

Over the past few months, the K8s (Kubernetes) Semantic Conventions SIG focused on stabilizing Kubernetes attributes used by OpenTelemetry Collector processors such as k8sattributes and resourcedetection . That work has now paid off: Kubernetes attributes have been promoted to release candidate status. Users can try this new schema via feature gates and provide feedback before the final stable release.
