⬆️ Upgrade Expo SDK to version 49 (#4)

Summary:
To ensure ongoing development and address security issues, Expo has been updated to version 49.

* 📌 Pin @react-aria/interactions to 3.16.0

I have discovered that react-aria is faulty.

Pinning the version with the overrides field in npm allows building

* 📌 Expo SDK set to 47

* 📌 Pin expo SDK to v49
