Update to expo 49 / RN 0.72

[sem4phor]

Description

When using nx expo I want to use the latest expo version which is from today 49 and react native 0.72. I guess the peer dependencies have to be upgraded and react native 72 introduced some monorepo featues maybe some things in the plugin need to be refactored because of that...

Maybe it is also worth considering adding expo-router v2 which was also released today to the generated app.

Motivation

Because expo 48 will be deprecated in 3 months and RN 72 solves huge performance issues and adds new monorepo features.
