After the Linux image is built and pulled, extract the resolved Azure Linux version from /etc/os-release and surface it as a pipeline warning in the build summary. This makes it easy to find the exact base image version for release notes without needing to kubectl exec into a running container or search through thousands of lines of build logs.

The warning log alone is sufficient for reading the Azure Linux version during release notes updates. No downstream pipeline step consumes the AZURELINUX_VERSION variable, so remove it. Assisted-by: Azure SRE Agent

Summary
After the Linux image is built and pulled on ci_prod builds, extract the resolved Azure Linux version from
/etc/os-releaseand surface it in the build summary as a pipeline warning.Why
The Azure Linux base image uses a floating tag (
mcr.microsoft.com/azurelinux/base/core:3.0), so its exact version can only be determined from the built container. Today, finding it requires either:kubectl execinto a running pod on a cluster that has the image deployedThis change makes the version visible directly in the ADO build summary alongside the existing image tag warning, making release notes updates straightforward.
