Throw an error during module initialization if the version of the "react-dom" package does not match the version of "react". We used to be more relaxed about this, because the "react" package changed so infrequently. However, we now have many more features that rely on an internal protocol between the two packages, including Hooks, Float, and the compiler runtime. So it's important that both packages are versioned in lockstep. Before this change, a version mismatch would often result in a cryptic internal error with no indication of the root cause. Instead, we will now compare the versions during module initialization and immediately throw an error to catch mistakes as early as possible and provide a clear error message.
