Bug 1462117 [wpt PR 11021] - Test short regionCode, a=testonly

Automatic update from web-platform-testsTest short regionCode (#11021)

With w3c/payment-request#690 the spec changed
requiring `regionCode` to just be the "code element" of an [[!ISO3166-2]]
country subdivision name (e.g., "CA" for California).
