As per our current behavior, Calendar current day will be
highlighted with the different Text color and same border / circle color as default.
By using, TodayTextColor property of MonthViewSettings in Calendar, we can change both the Current day TextColor
and BorderColor. Since, current day Text
color and Border are dependent and currently, we can’t change the current day
text color alone. Need to expose new API for current day BorderColor also.
