chore: migrate Example app & e2e tests to RN 0.72.4 (software-mansi…

…on#1880)

## Description

Migrate `Example` and e2e tests to the latest RN.
For some reason (I believe due to the presence and usage of v4) this app
was left behind with RN versions.

I did leave some `@react-navigation` components on v5 versions
(`bottom-tabs`, `drawer`, etc., because using more recent versions
caused e2e tests to fail), I'll try to upgrade these in separate PR.

## Changes

* Migrated `Example` app to `0.72.4`
* Bumped most of the dependencies to recent versions (also some of the
natives)
* Fixed detox configuration


## Test code and steps to reproduce

Build `Example` & check that it works + CI passes

## Checklist

- [ ] Ensured that CI passes
