fix: iOS version mismatch when using nightly prebuilds (#54370)

Summary:
Setting `ENV['RCT_USE_PREBUILT_RNCORE'] = '1'` when running nightlies on iOS will result in the following error:

The reason for this happening is that we precompile the iOS artifacts on CI using whatever version is set on main (by default version 1000). This works fine when using RCs and stable versions because before the publishing step we do a release commit (e.g https://github.com/facebook/react-native/commit/57ff54492f4a5a0e9d331e880b3c2264a2bd81f7), which updates the react-native version.

This can be easily mitigated by invoking the `set-rn-artifacts-version` CLI right before building the iOS prebuilds.
