[@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.

從 index.ios.js 中的 LocalNotificationsImpl.schedulePendingNotificationsNew() 開始，接著檢查 calendarWithMondayAsFirstDay() 以及報告中所示的 trigger 建構方式。在啟用佛教曆法的 iOS 14.4 上重現，並驗證 schedule() 能建立正常運作的通知，同時保留現有的重複行為。
