Summary [JSC] Remove redundant `isValidISODate` check in `TemporalCalendar`

The `isValidISODate` check after `regulateISODate` is redundant because: - When overflow is `Reject`, `regulateISODate` already calls `isValidISODate` and returns `std::nullopt` if invalid. - When overflow is `Constrain`, the month and day are clamped to valid ranges, so `isValidISODate` will always return true.
