CI-images:package_release: Fix SDK deployment
The markdown2 Python module was added to the package_release.py script, which resulted in a failed SDK deployment because it was missing from the build container. Updated ci-images to the latest revision, in which the module was added to the build container. Modified package_release.py to skip the metadata generation when deploying the SDK. Buildsdk and deploy step tested with an untagged pipeline.
