Broken tutorial links: old redis-master and redis-slave examples return 404

Several documentation pages still contain `kubectl apply` instructions pointing to the old `redis-master-*.yaml` and `redis-slave-*.yaml` example files (which were renamed to `leader` and `follower` for inclusive language). These links now return HTTP 404, breaking the tutorials for readers.

This affects pages like:
- `content/en/docs/tasks/configure-pod-container/translate-compose-kubernetes.md`
- `content/ja/docs/tutorials/stateless-application/guestbook.md`
- `content/id/docs/tasks/access-application-cluster/port-forward-access-application-cluster.md`
- ...and several other localized versions of `manage-deployment.md`, `labels.md`, and `volumes.md`.

I would like to open a PR to fix all remaining references across the content directories to use the new `leader` and `follower` file names.

/kind bug
/language en

Search the content directories for references to the old redis-master-*.yaml and redis-slave-*.yaml names, starting with the listed translate-compose-kubernetes.md, guestbook.md, and port-forward-access-application-cluster.md files. Update remaining localized tutorial references to the leader and follower names, then verify that no old references remain and the documented links no longer return 404.
