chore: update example app dependencies

[andrewsixsixsix]

Upgraded react-native version of example app from v0.68.2 to v0.69.12 react-native v0.69 required to update react-native-screens and react as well I followed this upgrade helper

Upgrade solves build failures which were fixed in late v0.68 and early v0.69 versions of react-native respectively (I experienced both when tried to run example app):

• Build error - use of bitwise '|' with boolean operands
• Build fails for Xcode 15 Beta 1 (and Beta 7)

Tested results with Xcode 15 and iOS 17 simulator/real device, all works great
