[Suggestion]: Documentation should be printable

Summary

Currently, the React documentation cannot be printed. Please add features for the documentation to be printable.

Details

I prefer reading documentation offline.

I'd like to add annotations. I want to read documentation from a book, not online.

まず、React ドキュメントサイトのスタイルと左メニューのエントリーポイントを確認し、現在の印刷出力と章のナビゲーションがどのように機能しているかに注目します。完了の条件は、ドキュメントを適切に印刷でき、左メニューの Download PDF オプションから複数ページにまたがる章またはトピック全体を生成できることです。
