Add useSelector and useDispatch example

[ivankoleda]

Description

This PR adds an example of usage useSelector and useDispatch. Mostly based on react-redux docs https://react-redux.js.org/using-react-redux/static-typing.

Hesitated about adding this types hooks in hooks folder, but there are examples of usage of react only hooks, so I added them into connected folder.
