build: add aliases for react-dom/server usage in server bundles (#55536)
Some people are using `ReactDOM/server` in some contexts like App Routes and Server Actions. The changes in #55362 made it so that there were no more aliases if they wanted to use it so it would fallback to their versions of React, which might not include the APIs you would expect from canary.
Also reverting the decision to proxy `ReactDOM/server` to `ReactDOM/server.edge` in the SSR layer as the APIs are not the same.
