Add community-eslint-plugin to eslint-config dependency (#27680)

Summary:
Added `react-native-community/eslint-plugin` as a dependency for `react-native-community/eslint-config`

The newly published eslint-config has `react-native-community/eslint-plugin` in its `.eslintrc`, but it's not listed under dependency, so when I try to use it in a community package, I'd have to install both `eslint-config` and `eslint-plugin`.
It would be nice to just be able to install `eslint-config` and extend that without additional package listed under devDependency.
