orchestration: use latest tag for k8s examples

Previously, we used specific version tags in our Kubernetes examples
(e.g., `v25.3.1`). This commit updates all Kubernetes example
configurations to use the `latest` tag for the CockroachDB image. This
simplifies maintenance of the release process.

Epic: none
Release note: none

 # CockroachDB on Kubernetes as a StatefulSet
 
 This example deploys CockroachDB on [Kubernetes](https://kubernetes.io) as a

 Kubernetes is an open source system for managing containerized applications
 across multiple hosts, providing basic mechanisms for deployment, maintenance,
 and scaling of applications.
