Revert "Fix Deadlock in RCTi18nUtil (iOS) (#31032)" (#32574)

[mmmoussa]

Summary

This reverts commit fcead14.

This should close #32509 . There was a bug where il8nManager.forceRTL() wouldn't work on app launch, and required an app restart. That was caused by an earlier change (#31032) which should not be necessary (the deadlock it was attempting to fix was actually caused by separate code).

Changelog

[iOS] [Fixed] - Fixed bug where forceRTL did not work on app launch

Pull Request resolved: #32574

Test Plan: Simple revert back to previously working code.
