This component was removed in facebook/react-native@0df92af. References to it need to be removed from navigation.md, and the navigatorios.md doc will need to be updated.

I believe that simply removing navigatorios.md from versioned_docs/0.58 and docs/ may not work, as Docusaurus might have trouble handling the removal. We may need to add a notice instead, explaining the component has been removed from core.
