Suggestion: Link each mention of a React API to the reference docs

I'm new to React and just started reading the documentation.

I noticed that references to the API are not links, just plain text. It would be helpful if they were actual links to the API.

Example: On this page https://reactjs.org/docs/rendering-elements.html it says:

The yellow API reference should actually be a link to the ReactDOM.render(), meaning a link to https://reactjs.org/docs/react-dom.html#render.
This helps me a lot because I can easily discover the complete reference of that function, the complete list and description of the parameters, function behaviors, different possible usage, etc.
As I go through the documentation and concepts, I can quickly go back and forth between concepts and API reference. It's much quicker to have links I can open in a new tab, instead of manually searching in the API reference every time.

從 issue 中指出的 rendering-elements 文件頁面開始，找到其中以純文字形式出現的 ReactDOM.render() 參照。檢查周圍的文件，找出其他需要進行相同處理的 API 提及；當這些參照連結到相應的 API 參考頁面時，即表示完成。
