Request for more detail/a deep dive section

Hey team,

Love the new Beta Docs!

Can you please provide a section (maybe a deep dive and/or a more reading link) explaining where the {children} value is coming from here and how it works:

export default function Section({ children }) {
  return (
    <section className="section">
      {children}
    </section>
  );
}

Link to doc: https://beta-reactjs-org-git-fx-fbopensource.vercel.app/learn/passing-data-deeply-with-context

It's obvious what it's doing but not how...

Cheers!

从链接的页面 /learn/passing-data-deeply-with-context 开始，找到定义 Section({ children }) 的示例。阅读周围的课程内容，解释 children 从何而来以及它是如何渲染的，然后添加一个深入探讨或延伸阅读部分；当示例的数据流对读者来说清晰时，就算完成。
