Summary:
I'm backporting PR https://github.com/facebook/react-native/pull/33945 to main
as it was merged on the release branch to unblock 0.69.
Those changes are necessary as Hermes was not being donwloaded at all during `pod install`
on .69 and the app was failing to build with a missing `hermes/hermes.h` import.
Changelog:
[iOS] [Fixed] - Fix Hermes not being properly downloaded during pod install
