[FEAT] Remove moment lib from Datepicker

[frgiovanna]

Is your feature request related to a problem? Please describe.

The Datepicker component is using the moment library as a dependency. This lib was deprecated and its own documentation gives advice to finding another lib to do the same as it does.

Describe alternatives you've considered

We can use the date-fns lib, which is a great and well-maintained one, and use its format function the same way we're doing with the moment.

On the Datepicker component:

import { format } from 'date-fns';

// ...

  return (
      startD && (
        <Input disabled={disabled}>
          {format(startD, dateFormat)}
          {endD && ` - ${format(endD, dateFormat)}`}
        </Input>
      )
    );
