-Starting from 0.73, react-native.config.js is created by CLI during the init process.
-It contains automaticPodsInstallation flag set to true by default.
-This flag is used by CLI to determine whether to install CocoaPods dependencies when running ios commands or not.
-It's created by CLI rather than being a part of a template to avoid displaying this file in the Upgrade Helper,
-as it might bring confusion for existing projects where this change might not be applicable.
-For more details, see https://github.com/react-native-community/cli/blob/main/docs/projects.md#projectiosautomaticpodsinstallation
