[Suggestion]: portals caveat

Summary

The problems solved by portals can also be solved by the dialog element, popover API and anchor positioning.

I think it is worth mentioning that on the page less people think the only approach is to use portals.

I don’t think native popovers are perfect. There will probably always be a need for this portal API, but I think the main example shouldn’t be a modal. That genuinely is better solved with the native HTML element.

I’m not suggesting a large new section, just a brief note to say there are other approaches.

打开 issue 中链接的 React DOM createPortal 参考页面，查看其中的 modal 示例及其周围的说明。添加一条简短说明，承认 dialog、popover 和 anchor 定位是原生替代方案，然后确认该页面明确将 portal 作为一种选项，而不是唯一的方法。
