Update the React-Router example to the latest version i.e. v5 or v6

[sohamsshah]

Currently the React Router example is having version: react-router-dom": "^4.3.1.

Summary

• Will update the example as there are some major API changes while migrating to v5 or above compared to v4.
• Will also include Private/Protected Routing in the example itself so the developers can get better understanding overall.
• Would love to add some newer components too in this example, so to keep things up to date.

Justification

As a developer exploring any open source library, one of the first things one searches for is example folder. This PR will help to keep things up-to-date!

Available extra resources

• Can you affirm what version shall I opt for? (v5 or v6)
  v6 is going to be released soon and already have started being used by many.

• Can you affirm what must-add components shall I include in the example?

Carbon is a collaborative system. We encourage teams to build components and
submit them for integration as either add-ons or core components.

Looking forward to be an active contributor to the community. Will be active in raising PR and fixing this.
Thanks,
