[@nativescript/local-notifications] Schedule not work on iOS with Buddhist calendar

Dear sir,
I had upgraded my app to NativeScript 7 and the notification (@nativescript/local-notifications, version 5.1.0) does not work on iOS (14.4). After debugging all day, I found that LocalNotifications.schedule() not work because my iPhone is set the calendar to Buddhist.

The bug is in the index.ios.js file, in the method schedulePendingNotificationsNew() of class LocalNotificationsImpl as part of code below:

 // Notification trigger and repeat
 let trigger;
 if (options.at) {
   const cal = NSCalendar.currentCalendar;  //LocalNotificationsImpl.calendarWithMondayAsFirstDay();
   const date = cal.componentsFromDate(LocalNotificationsImpl.getInterval(options.interval), options.at);
   date.timeZone = NSTimeZone.defaultTimeZone;
   trigger = UNCalendarNotificationTrigger.triggerWithDateMatchingComponentsRepeats(date, options.interval !== undefined);
 }
 else {
   trigger = UNTimeIntervalNotificationTrigger.triggerWithTimeIntervalRepeats(2, false);
 }

At the line 137, the LocalNotificationsImpl.calendarWithMondayAsFirstDay() which return ISO8601 (Gregorian) calendar make a wrong matching trigger. So, I change the code to use the NSCalendar.currentCalendar and It work well.

从 index.ios.js 中的 LocalNotificationsImpl.schedulePendingNotificationsNew() 开始，然后检查 calendarWithMondayAsFirstDay() 以及报告中所示的 trigger 构造方式。在启用佛教历法的 iOS 14.4 上复现，并验证 schedule() 能创建正常工作的通知，同时保留现有的重复行为。
