Enable support to show all dates on Month's Datepicker

I'm trying to enable all data on month calendar but does not work.

I think we can have a option to don't hide some dates.


(The red dates aren't showed by default month datepicker)

#### What is the use-case or motivation for this proposal?

On the advertiser market, the weeks are measured by week, because of this style the users have to navigate between the months to see the full calendar.

Comienza localizando la implementación del selector de fechas mensual y sus pruebas existentes. Revisa cómo se gestionan las fechas fuera del mes mostrado, luego define el comportamiento esperado de la opción para mostrarlas y verifica el resultado con el caso de uso del calendario del anunciante.
