Fix Adar month name in Hebrew calendar (#16697)

The returned data from ICU has 6th month name as 'Adar I' and 7th month name as 'Adar'
We need to adjust that in the list used with non-leap year to have 6th month as 'Adar' and 7th month as 'Adar II'
note that when formatting non-leap year dates, 7th month shouldn't get used at all.
