Build Tools: Use umd builds provided by React instead of bundling our own builds.

We tried moving away from the deprecated React UMD builds previously,
the problem we faced is that there's a warning that is triggered on the console because we're not using a separate impact for `createRoot`.

This warning has been removed in React 19 along with the removal of the UMD builds, so we should be able to revert this commit when we upgrade to React 19 but for now, we need to restore the usage of the umd builds.

Props mamaduka.
