Cleanup orchestration documents (#5623)

- Remove hostPort from Kubernetes deployment example docs. Initially
hostPort was added to ensure Minio pods are allocated to separate
machines, but as per latest Kubernetes documents this is not
recommended approach (ref: https://kubernetes.io/docs/concepts/
configuration/overview/#services). To define pod allocations,
Affinity and Anti-Affinity concepts are the recommended approach.
(ref: https://kubernetes.io/docs/concepts/configuration/assign-pod-node)

- Add Minio release tag to Docker-Compose example file.
