Refactor generate-artifacts-executor.js: remove configFileDir CLI argument, use node resolution instead (#41557)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/41557

The `configFileDir` CLI argument is used to help to find paths to the 3rd party dependencies of the app. Since we only care about dependencies listed in the root `package.json`, we can use `node` resolution instead of having to construct paths manually. In that case `configFileDir` becomes redundant.

Changelog: [iOS][Breaking] - Delete configFileDir CLI argument.
