Add --skip-expo option to skip Expo versioning even if detected

[sregg]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-version@4.0.0 for the project I'm working on.

We have a vanilla React Native app that uses expo-updates. We don't need to update app.json but we do need to update the native files (i.e. Info.plist and build.gradle). I added a new option --skip-expo to manually skip expo versioning even if detected.

Here is the diff that solved my problem:

Great! Definitely we need this feature too!

Same, this would be very useful for us too.
