feat: add more react-query examples

[marceloschreiber]

Description

Add more operations showing how to use react-query.

This breaks the integration with json-server.

json-server is not capable of handling the creation of new To-dos and paginating them as we would like.

So I created a simple Spring Boot backend while developing these changes.

@LuisValgoi what do you think we should proceed?
