Intl.NumberFormat notation not implemented on iOS

[andreialecu]

Problem

See code below:

let formatter = Intl.NumberFormat('en', { notation: 'compact' });
formatter.format(10000) -> returns 10K on Android, but 10,000 on iOS

Hey @andreialecu, thanks for reporting this. Closing this as a duplicate of #1035.

We're definitely aware of the current gaps in our Intl implementation, and are actively investigating ways to close them in the coming months.
