[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.

從 issue 中提到的 react.dev/reference/react-dom 頁面開始，將目前的 unstable_batchedUpdates 文件與其現代模式和 legacy 模式下的行為進行對照審查。完成標準是頁面說明 batching 在何時有效、指出可能出現 no-op 行為，並明確說明開發者是否應該使用它。
