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

[opcodewriter]

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.

Good suggestion! I know we do this in some places but we're not consistent about it.

Any interest in submitting one or more PRs to add links in places where it would be relevant?
