Summary of Changes

Hello @amcolin, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the Google Cloud Vision API sample code to utilize the BatchAnnotateImages method, replacing the deprecated DetectLogos call. This ensures the samples remain functional, demonstrate current best practices, and maintain compatibility with the latest client library, thereby enhancing the reliability of the vision samples.

Highlights

• API Migration: The DetectLogos function has been replaced with BatchAnnotateImages from the cloud.google.com/go/vision/v2/apiv1 package, addressing its deprecation within the client library.
• Image Handling Update: The method for preparing images for API calls has been updated to align with the BatchAnnotateImages method's requirements, now using visionpb.Image with Content for local files and Source for URIs.
• Response Parsing Adjustment: The code now iterates through response.Responses to correctly parse the results from the BatchAnnotateImages call, including error handling for individual responses.

Code Review

This pull request correctly replaces the deprecated DetectLogos call with the BatchAnnotateImages call from the v2 API. The implementation looks good, but I've noticed a minor typo in a variable name in both of the updated functions. I've left suggestions to correct it. Otherwise, the changes are solid.
