[Vertex AI] Remove golden-files directory (#6740)

Remove the `firebase-vertexai/src/test/resources/golden-files`
directory. This was carried over from the
[`generative-ai-android`](https://github.com/google-gemini/generative-ai-android)
repository. We are now using
https://github.com/FirebaseExtended/vertexai-sdk-test-data/tree/main/mock-responses
instead.
