[Bug]: Missing clarification for unstable_batchedUpdates behavior

Summary

The documentation does not clearly explain the current behavior of unstable_batchedUpdates, which can be misleading for developers.

Details

While reviewing the React DOM source code, I noticed that unstable_batchedUpdates may behave as a no-op in modern React configurations (outside of legacy mode). However, this behavior is not clearly explained in the documentation.

This can lead developers to assume that the function still provides batching behavior, when in practice it may not affect updates in modern setups.

Suggested improvement:

• Clarify when unstable_batchedUpdates is effective
• Indicate that it may behave as a no-op in modern React
• Provide guidance on whether it is still recommended for use

This would help prevent confusion and improve developer understanding of the API.

从 issue 中提到的 react.dev/reference/react-dom 页面开始，将当前的 unstable_batchedUpdates 文档与其现代模式和 legacy 模式下的行为进行对照审查。完成标准是页面解释 batching 在何时有效，指出可能出现 no-op 行为，并明确说明开发者是否应该使用它。
