Disable react-in-jsx-scope rule in eslint config (#46587)

Summary:
All newly generated react native apps are still showing warnings to use react in the jsx scope. That is not needed anymore as of react 18 with built-in jsx transform plugin.

Reproduction: https://github.com/matinzd/react-in-jsx-warning-repro

Run `npm run lint` in this repo.

## Changelog:

[GENERAL] [FIXED] - Disable `react-in-jsx-scope` rule in eslint config

Pull Request resolved: #46587

Test Plan: Initiate a new template with community CLI and you should not see this warning anymore.
