Ricky e9ae2c8f35 Clean up console.log tests (#28693)
Followups to https://github.com/facebook/react/pull/28680

One of these test don't need to use `console.log`. 

The others are specifically testing `console.log` behavior, so I added a
comment.

react

React is a JavaScript library for creating user interfaces.

The react package contains only the functionality necessary to define React components. It is typically used together with a React renderer like react-dom for the web, or react-native for the native environments.

Note: by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages. Don't forget to use the production build when deploying your application.

Usage

import { useState } from 'react';
import { createRoot } from 'react-dom/client';

function Counter() {
  const [count, setCount] = useState(0);
  return (
    <>
      <h1>{count}</h1>
      <button onClick={() => setCount(count + 1)}>
        Increment
      </button>
    </>
  );
}

const root = createRoot(document.getElementById('root'));
root.render(<Counter />);
