Fix #8052 year not updated with viewDate changes

Fix #8052
The issue occurred when we set the view date and deleted the input field. The currentYear variable retained the old value (in this case, 2000).

primereact/components/lib/calendar/Calendar.js

Lines 3391 to 3393 in d57bbb7

	const viewDate = getViewDate();
	const viewYear = viewDate.getFullYear();
	const displayYear = props.numberOfMonths > 1 || props.yearNavigator ? metaYear : currentYear;

I adjusted displayYear to use metaYear, which fixes the issue, and the yearNavigator works correctly. However, if we modify the value of InputRef.current.value in a way that it cannot be parsed as a Date, the rendering will fall back to using ViewDate as the parameter.
