Remove prettier from dependencies (#33125)

Summary: `prettier` should not be declared in dependencies in the ESLint config because it can trigger issues when a different version is installed on the client app. `prettier` is already declared as `peerDependencies` and in the [README](https://github.com/facebook/react-native/blob/main/packages/eslint-config-react-native-community/README.md), it's explicitly asked to install it: ``` yarn add --dev eslint prettier react-native-community/eslint-config ``` ## Changelog <!-- Help reviewers and the release process by writing your own changelog entry.
