Update React Router Lesson

[wvmitchell]

Lesson to be updated: React Router

Summary of changes needed:

• The current lesson uses React Router 5
• Once hooks are the default for M3, this needs to be updated to React Router 6, which works with hooks. There is an existing lesson that was started for Router v6 - needs reviewed and possibly updated.
• Throughout the application there are code snippets, links, and documentation that all point towards Router 5. The lesson will need to be combed for those items, and updated as necessary.
