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.

Start with the rendering-elements documentation page named in the issue and locate the plain-text ReactDOM.render() reference. Review the surrounding documentation for other API mentions that need the same treatment; done means those references link to the corresponding API reference pages.
