react-native iOS settings may not be defined with new architecture

[quinnturner]

Describe the bug

For settings.AppleLocale, settings can be null/undefined using the new arch, so I think we also need a check _a.settings?.AppleLocale

To reproduce

When I loaded my application using React 0.77 with the new architecture on an iOS simulator with the latest iOS version settings was undefined or null

Expected behavior

Check for nullability on settings

SDK version
Latest

Hey @quinnturner, do you know if it is ever non-null (for instance on a real device)? I can approve your PR for now, but my concern here is that the code may actually need re-structured to make this call at a different time, or with a different API. So I will likely leave this issue open even after merging the PR until that behavior can be validated.

Honestly, I know very little about this code. I had to use this patch to get new arch to work but besides that, I have zero insights. Sorry!

[kinyoklion]

Ok. Just be aware that if you are using auto-environment attributes for targeting, that this value could be missing with this change.
