fix: link to react documentation (#43704)

* Update set-state-with-this.setstate.md

revert the base url back to https://facebook.github.io/react/docs/state-and-lifecycle.html

* Update use-proptypes-to-define-the-props-you-expect.md

Linked to the exact place for the types of propTypes you can use. The original link was to the documentation, which states that it has been moved, So I thought it would be intuitive to link the exact place React wants you to go.

* Update curriculum/challenges/english/03-front-end-development-libraries/react/use-proptypes-to-define-the-props-you-expect.md

-React expects you to never modify `state` directly, instead always use `this.setState()` when state changes occur. Also, you should note that React may batch multiple state updates in order to improve performance. What this means is that state updates through the `setState` method can be asynchronous. There is an alternative syntax for the `setState` method which provides a way around this problem. This is rarely needed but it's good to keep it in mind! Please consult the [React documentation](https://facebook.github.io/react/docs/state-and-lifecycle.html) for further details.

-In the example above, the `PropTypes.func` part checks that `handleClick` is a function. Adding `isRequired` tells React that `handleClick` is a required property for that component. You will see a warning if that prop isn't provided. Also notice that `func` represents `function`. Among the seven JavaScript primitive types, `function` and `boolean` (written as `bool`) are the only two that use unusual spelling. In addition to the primitive types, there are other types available. For example, you can check that a prop is a React element. Please refer to the [documentation](https://reactjs.org/docs/jsx-in-depth.html#specifying-the-react-element-type) for all of the options.
