Add troubleshooting guide for yoga module errors

Browse Source 
Summary: Tried to sum up all solutions mentioned in https://github.com/facebook/react-native/issues/28503 for this recurring problem. The most common problem being simply opening the wrong file in XCode. From experience I can tell this is not obvious for iOS noobs like me :-P.

1. Make sure that the simulators are spawned by your current Xcode version. Force quite all simulators, run `sudo xcode-select --switch /Applications/Xcode.app` (update path were necessary), and start simulators & Flipper again.
1. Make sure the iOS build target version aligns with the podfile and target iOS 11. [Example](https://github.com/facebook/react-native/issues/28503#issuecomment-696026013)
