In-Depth Explanation of React Version Handling Doc (#89426)
There have been multiple discussions and some confusion around [React
version handling](https://nextjs.org/docs#react-version-handling) in
Next.js. This PR adds an in-depth explanation to clarify how React and
react-dom versions are managed internally, and why they still need to be
declared in package.json.
The goal is to help developers better understand this behavior and
reduce recurring questions around it.
