[RFC] - Improve documentation

[morrys]

• comparison with other form libraries
  • dynamic configuration, it is not necessary to define and manage all the fields when the form is created.
  • you use Relay, you don't need other state management libraries
  • the size of the bundle is very small as all the APIs that Relay makes available are used
  • the rendering is super performing, each field is managed independently of the others They are dynamically subscribed using the useFormSetValue hook
• adding example to .README
• adding examples on top instead of types in the different documentation of hooks
