Some weird things in the diff that aren't really changes from main - probably related to cherry-picking.

LGTM on green

Please merge from the command line so we end up with the commit history in main

@paulb777 Agreed that it's likely from the cherry-picking. I also noticed some weird things when diffing vertex-ai...ah/vertex-ai in the GitHub web UI that I don't see locally, e.g., FirebaseVertexAI/Tests/Unit/GenerateContentResponses/unary-failure-image-rejected.json shows as a new file despite existing in both vertex-ai and ah/vertex-ai.
