Document using HTML dialog element

Modals/Dialogs are very common on the web. Now that the HTML dialog element has full cross-browser support it would be great to see documentation around how to use this in React as it is far from obvious. In the current docs it says "instead of exposing open() and close() methods on a Dialog component, pass an isOpen prop to it." Should people avoid using the showModal() function? Is it necessary to use portals when using a HTML dialog element?

Such a common UI task should be clearly documented.

<dialog> used to have some accessibility concerns but all of those have been addressed. It's now a much better option than implementing your own dialog. It has many accessibility features like 'inert' built-in.

未指定文档文件或测试。首先查看 issue 中引用的当前 React 文档指南，然后调查 HTML dialog element、showModal() 和 portals 应如何结合使用。当 React 文档清楚地解释推荐的方法，并回答是否需要 showModal() 和 portals 时，即视为完成。
