Enhance with redux thunk example (#13576)
* Refactored the store so that it doesnt use getInitialProps

* Applied the changes in the _app file

* Refactored the wrapper so that it uses the new store flow

* Removed the old redux syntax

Instead of passing the state from the parent component, I have used the new redux hooks to retrieve the current state.

* The clock no longer requires state to be passed too

* Updated the variable names

* forgot to bring back hot reloading

* Applied requested change.
