Calendar: Incorrect TypeScript typing of date slot

[James-Laidlaw]

Describe the bug

The date slotprop of the calendar is incorrectly typed as

type CalendarValueType = Date | Date[] | undefined;

when the documentation and behavior suggests it is a date representation metadata object with a structure looking more like
{ day: number; month: number; year: number; today: boolean; selectable: boolean }

this causes typescript to throw errors when you use it as intended.

Steps to reproduce the behavior

1. make a calendar

2. attempt to format it something like this

  <Calendar :inline="true" class="testing123">
    <template #date="slotProps">
      {{ slotProps.date?.day }}
    </template>
  </Calendar>

3. observe typescript throwing errors about it being typed as
