feat(genai): Multiple updates to improve samples quality, consistency…

… and readability (#13157)

* feat(genai): Update Gen AI SDK Samples for Consistency/Readability

- Updated to latest SDK version
- Added Typing and consistent imports
- Changed all GA Samples to include `HttpOptions` for `v1` endpoint
- Updated Gemini 2.0 Exp to Gemini 2.0 Flash GA
- Updated Batch Prediction to Gemini 2.0 GA

* Fix issue with PIL Image load

* Rename BatchPredict Files
