docs(Datepicker): update documentation + stories

[cf-remylenoir]

Purpose of PR

This work takes care of updating our Documentation and Storybook based on the latest API changes.

Documentation

• Example of setting a date range
• Example of setting multiple months in view

Storybook

• Addition of the weekStartsOn prop to the Controls
  • I had to define the arg types manually since Storybook is not inferring all the props from the component, even tho the @storybook/addon-essentials is installed and should take care of it.
