Test Unicode extension subtags where the ukey subtag contains a digit.

8.2.1 Intl.getCanonicalLocales (locales)
|

1. Let ll be ? CanonicalizeLocaleList(locales).
|

2. Return CreateArrayFromList(ll).

9.2.1 CanonicalizeLocaleList (locales)

7. Repeat, while k < len

c. If kPresent is true, then

v. If IsStructurallyValidLanguageTag(tag) is false, throw a RangeError exception.

vi. Let canonicalizedTag be CanonicalizeUnicodeLocaleId(tag).
