- Bump CLI to ^3.0.0 (#27235 )
Summary: Upgrading CLI to latest. It's likely not yet compatible with master, because we depend on Metro 0.56, and master is on 0.57. This diff is intended to be cherry-picked to 0.61 and 0.62. cc grabbou ## Changelog [Internal] [Changed] - Bump CLI to ^3.0.0 Pull Request resolved: https://github.com/facebook/react-native/pull/27235 Test Plan: None Differential Revision: D18527709 Pulled By: cpojer fbshipit-source-id: 44448058c48a66d22a1d71abdc908f532f5aa547

 ## Contributing Code

-Code-level contributions to React Native generally come in the form of [pull requests](https://help.github.com/en/articles/about-pull-requests). These are done by forking the repo and making changes locally. Directly in the repo, there is the [`rn-tester` app](/packages/rn-tester) that you can install on your device (or simulators) and use to test the changes you're making to React Native sources.

-The process of proposing a change to React Native can be summarized as follows:
-
-1. Fork the React Native repository and create your branch from `main`.
-2. Make the desired changes to React Native sources. Use the `packages/rn-tester` app to test them out.
-3. If you've added code that should be tested, add tests.
-4. If you've changed APIs, update the documentation, which lives in [another repo](https://github.com/facebook/react-native-website/).
-5. Ensure the test suite passes, either locally or on CI once you opened a pull request.
-6. Make sure your code lints (for example via `yarn lint --fix`).
