chore: Remove legacy version check in `react-native.config.js`

[lukmccall]

Description

Removes legacy version check from react-native.config.js.

Changes

The community CLI is no longer a dependency for React Native, meaning it may not be installed in every project. For example, projects that use Expo won't include the @react-native-community/cli-* packages. Consequently, this check will fail, leading to issues with autolinking components.

This version check can be removed safely, as the 9th version of the CLI was released two years ago.

Test code and steps to reproduce

This change was tested using expo project on react native 0.76.
