docs: Get combined interval pattern using a given pattern and the fallback interval pattern.
  
  If a skeleton based pattern is not available or not wanted, this method can be used to create an interval
  pattern based on a given pattern, using the fallback interval pattern.
  
  @param {string} sPattern the single date pattern to use within the interval pattern
  @param {sap.ui.core.CalendarType} [sCalendarType] the type of calendar. If it's not set, it falls back to the calendar type either set in configuration or calculated from locale.
  @returns {string} the calculated interval pattern
