[native] Bump react-native-screens to 3.29.0

Summary: This is the latest version that I was able to get to work with our setup. More details here.

Test Plan: CI and tested running the Android app on simulator. Before releasing this I'll test a release build on physical iOS and Android devices and play around with it a bit
