Greptile Summary

This PR updates the Node Feature Discovery component reference. The main changes are:

• Sets the Network Operator Helm default NFD image tag to 5d6187d5.
• Sets the NFD release metadata version to 5d6187d5.
• Keeps the generated values path aligned with the release metadata.

Confidence Score: 4/5

Default NFD deployments can fail if the staging registry does not contain the short-SHA image tag.

• The changed Helm value is used directly as the NFD container tag.
• The new tag differs from the release-style tag used before.
• The metadata change matches the Helm value, so the main risk is image availability rather than config drift.

Short-SHA Image Tag

This value is rendered directly into the NFD workloads as nvcr.io/nvstaging/mellanox/node-feature-discovery:5d6187d5. If nvstaging only publishes this component under the release-style network-operator-* tag, default Helm installs will leave the NFD master, worker, GC, and topology-updater pods in ImagePullBackOff.
