[dev-menu][iOS] Fix reloading app through "r" hotkey

[gabrieldonadel]

Why

Closes ENG-12058

Similar to the issue reported by @Kudo on core (facebook/react-native#44241), triggering two immediate reloads when running an app using the new arch in bridgeless mode will cause the app to crash on iOS as well.

How

Instead of registering the "r" hotkey for the DevMenu reloadAction we can just rely on the default react-native reload action (which also uses the "r" hotkey)

Test Plan

Test dev-client through BareExpo and FabricTester

Checklist

• Documentation is up to date to reflect these changes (eg: https://docs.expo.dev and README.md).
• Conforms with the Documentation Writing Style Guide
• This diff will work correctly for npx expo prebuild & EAS Build (eg: updated a module plugin).

thanks! this should be fine for now, but i wonder if we should be disabling all of the built-in react-native keyboard shortcuts rather than removing ours. we may want to revert this later
