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.

Aucun fichier de documentation ni aucun test n’est nommé. Commencez par examiner les indications actuelles de la documentation React citées dans l’issue, puis étudiez comment HTML dialog element, showModal() et portals doivent être utilisés ensemble. Le travail est terminé lorsque la documentation React explique clairement l’approche recommandée et répond à la question de savoir si showModal() et portals sont nécessaires.
