[Tooling] Update critical artifact list (#28966)

When a React PR is opened CI will report large size changes. But for
critical packages like react-dom it reports always. In React 19 we moved
the build for react-dom the client reconciler from react-dom to
react-dom/client

This change adds react-dom-client artifacts for stable and oss channels
since that is originally what was being tracked. But since
react-dom/client always imports react-dom I left the original react-dom
packages as critical as well. They are small but it would be good to
keep an eye on them
