[dev-menu][iOS] Fix reloading app through "r" hotkey (#28617)

# 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
