Fix for iOS displaying a RedBox for LogBox handled errors (#32641)

Summary:
Fix for iOS displaying a RedBox for LogBox handled errors, this has been happening since RN 0.65 (in 64.2 and earlier, if it was handled by LogBox then it wouldn't trigger RedBox)

Fixes #32106

## Changelog

[iOS] [Fixed] - Stop RedBox from appearing for LogBox handled errors

Pull Request resolved: #32641

Test Plan: Manually tested. Seems to fix things (and RedBox still displays for things like 'Could not connect to development server') but I would appreciate RSNara or someone else who is more familiar with the code to confirm that the original switch was a mistake and not something deliberately changed.
