[Idea]: Add second `expo prebuild` app + eas build --local & eas submit github pipelines

[ice-chillios]

Hi, First of all I wanted to thank you for this example as lately I used this as base for my monorepo in which I had 2 mobile apps, web, ui & shared functionalities.

After migration I had couple of issues like react-native-reanimated/react-native-gesture-handler multiple versions (probably happens whenever you have 2 or more apps with those deps) + it wasn't fully prepared for "ejected" flow in monorepo.

I propose to add additionally one more expo with prebuild app to this pipeline.
Additionally I can add example with github actions eas build --local & eas submit workflow.
