Subject: [PATCH] [processor/k8sattributes] Update README.md (#34950)

**Documentation:**

Update README for Kubernetes Attributes Processor to indicate
`container.id` attribute is available if `k8s.container.name` is
provided.
I followed
https://docs.appdynamics.com/observability/cisco-cloud-observability/en/application-performance-monitoring/monitor-applications-in-kubernetes/infrastructure-correlation#InfrastructureCorrelation-KubernetesPodContainerID
and it's working.
