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.

Keine Dokumentationsdatei oder kein Test wird genannt. Beginne damit, die im Issue zitierte aktuelle React-Dokumentationsanleitung zu prüfen, und untersuche anschließend, wie das HTML dialog element, showModal() und portals gemeinsam verwendet werden sollten. Als erledigt gilt die Aufgabe, wenn die React-Dokumentation den empfohlenen Ansatz klar erklärt und die Frage beantwortet, ob showModal() und portals notwendig sind.
