Invalid numberingSystem tests

[longlho]

Hi there,

While working on Unified NumerFormat polyfill I noticed #2383 which might not be valid as numberingSystem is not retrieved anywhere in current spec and proposed unified numberformat. The closest call was the iteration over options in https://tc39.es/ecma402/#sec-resolvelocale but that's not enough to trigger a getter. Should those tests be modified?

Thanks,

The test is for tc39/ecma402#175, which adds those options and how to read them in Intl objects.

Gotcha thanks!
