fix(emulators): Fix listing emulator targets

[dpogue]

Platforms affected

iOS

Motivation and Context

I think I accidentally broke this during earlier refactoring for 8.0.0, but it was now trying to (and incorrectly) listing the simulator devices rather than the simulator device/runtime combinations.

Description

Restore the correct listing for simulator devices/runtimes when using cordova run ios --list

Testing

Tested running npx cordova run ios --list and ensured the output matched between these changes and 7.1.1

Checklist
