Scheduler for Blazor

Description

I need to hide the dates from other months in the Scheduler component's current month view because it may confuse the users.

Solution

To hide the dates from other months in the month view of the Scheduler component:

1. Define SlotTemplate.
2. Use an if block to render conditionally the dates based on the selected month.
