[issue35406] calendar.nextmonth and calendar.prevmonth functions doesn't check if the month is valid

[Serhiy Storchaka]

nextmonth() is not a public API. You should not use it.

If you want to make IllegalMonthError be always raised instead of IndexError for out of range month values, this is a different issue.
