Summary

Validate that the existing UBI9-based images run correctly on RHCOS10 cluster nodes without any changes.

RHCOS10 ships with RHEL10 as its host OS. This PR triggers CI against an RHCOS10 cluster to confirm
UBI9 containers remain compatible before committing to a base image migration.

No Dockerfile changes. This is a baseline/smoke test only.

Follow-up

If CI passes → PR2 migrates all base images from UBI9 to UBI10.

Add documentation to track the RHCOS10 baseline compatibility test.
No Dockerfile changes — this PR validates existing UBI9-based images
run correctly on RHCOS10 cluster nodes before migrating to UBI10.

currently use `registry.access.redhat.com/ubi9/ubi-minimal:9.6` or
`registry.access.redhat.com/ubi9/ubi:9.5`" so it matches the table entries that
also reference `ubi9/ubi-minimal:latest`: either add `:latest` to the list

images vs CI images (e.g., "product images use 9.6/9.5; CI images use
ubi9/ubi-minimal:latest") ensuring the sentence near the top and the CI image
rows in the table are consistent.

⚠️ Potential issue | 🟡 Minor

Clarify base-image version statement to match the table.

Line 18–19 says all images use only 9.6/9.5, but Line 28–29 lists CI images on ubi9/ubi-minimal:latest. Please update the sentence to include latest (or split product vs CI image wording) so the document is internally consistent.

Also applies to: 28-29
