chore: remove the use of deprecated types from VertexTaskStore (#889)

[gaborfeher]

• vertexai.Part & co. will be replaced soon by genai.Part & co.
• It's better to use the more specifically named variants of Task and Status: A2aTask and A2aTaskStatus.

Summary of Changes

Hello, 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 refactors the VertexTaskStore to utilize current and more semantically appropriate type definitions. The primary goal is to migrate away from deprecated vertexai.Part and generic vertexai.types.State in favor of google.genai.Part and vertexai.types.A2aTaskState, respectively. This update ensures the codebase remains aligned with evolving SDKs and improves the maintainability and clarity of task and part conversions.

Highlights

• Type Migration: Replaced deprecated vertexai.Part types with google.genai.Part for improved compatibility with the Generative AI SDK.
• Task State Refinement: Updated vertexai.types.State to the more specific vertexai.types.A2aTaskState for task status definitions, enhancing clarity and precision.
• Codebase Update: Modified function signatures, type hints, and object instantiations across the vertex_task_converter.py module to reflect the new type definitions.
• Test Alignment: Updated unit tests to assert against the newly adopted google.genai.Part and vertexai.types.A2aTaskState types, ensuring correctness of the conversions.

Code Review

This pull request updates the Vertex task converter to use more specific and modern types from the vertexai and google.genai libraries. The deprecated vertexai.Part is replaced with genai.Part, and the generic vertexai.State is replaced with the more specific vertexai.A2aTaskState. These changes are applied consistently across the converter and its tests. A defensive check for None has also been added when processing inline data, which improves robustness. The changes are correct and improve the code's clarity and maintainability.
