chore: update the example-project to use latest react-native setup

[fadi-george]

Description

One Line Summary

• updates the react-native example to use the latest react-native package and configurations

---

Details

• deleted original RN example project and set it up with latest versions
• removed material ui package for react native example since the package was really old and was giving errors
• updated bundle id and team for signing settings

Motivation

• Was experiencing tons of errors just getting the example running on mian. The example project is very outdated and so needs an update/upgrade.

Manual testing

• May need to run npm run build first in root folder.
• Run pod install in ios examples folder. Then npm run ios to see ios example running.
• Ensure you have Android Home setup. Then npm run android to android example running.

Checklist

Overview

• I have filled out all REQUIRED sections above
• PR does one thing
  • If it is hard to explain how any codes changes are related to each other then it most likely needs to be more than one PR
• Any Public API changes are explained in the PR details and conform to existing APIs

Testing

• I have included test coverage for these changes, or explained why they are not needed
• All automated tests pass, or I explained why that is not possible
• I have personally tested this on my device, or explained why that is not possible

Final pass

• Code is as readable as possible.
  • Simplify with less code, followed by splitting up code into well named functions and variables, followed by adding comments to the code.
• I have reviewed this PR myself, ensuring it meets each checklist item
  • WIP (Work In Progress) is ok, but explain what is still in progress and what you would like feedback on. Start the PR title with "WIP" to indicate this.
