This is an editorial change in the Intl spec. See: https://github.com/tc39/ecma402/commit/087995c https://github.com/tc39/ecma402/commit/233d29c This also adds a missing spec link for the sanctioned units and fixes a broken spec link for IsSanctionedSingleUnitIdentifier. In LibUnicode, the NumberFormat generator is updated to use the constexpr helper to retrieve sanctioned units.
