[Documentation]: Always use FQDM for container images

Description of errors

Documentation Issue: Device Config Manager Image Missing FQDN

Documentation Page

https://instinct.docs.amd.com/projects/gpu-operator/en/latest/dcm/applying-partition-profiles.html

Problem

The documentation uses a non-FQDN image reference that fails in OpenShift and other environments with short name enforcement:

image: "rocm/device-config-manager:v1.4.0"

Error

Warning  InspectFailed: Failed to inspect image "": rpc error: code = Unknown desc = short name mode is enforcing, but image name rocm/device-config-manager:v1.4.0 returns ambiguous list

Solution

Use the fully qualified domain name:

image: "docker.io/rocm/device-config-manager:v1.4.0"

Impact

• Blocks users on OpenShift/Podman environments with short name enforcement
• Affects the kubectl patch deviceconfig command in the "Enabling Device Config Manager" section

Environment

• OpenShift 4.x
• Podman/CRI-O with short name enforcement enabled

Attach any links, screenshots, or additional evidence you think will be helpful.
