402: Replace currency-digits.js Intl.NumberFormat test (#4285)

Browse Source 
ISO 4217 no longer normative for currency minor digits. New test verifies that
currency data (from whatever source) is used by verifying that `maximumFractionDigits` and `minimumFractionDigits`
are identical. See https://github.com/tc39/ecma402/pull/922
