This change introduces a new sample agent and documentation to demonstrate the usage of the `VertexAiCodeExecutor`.
The new agent, located at `vertex_code_execution/agent.py`, is a direct counterpart to the existing sample at `code_execution/agent.py`. The key difference is that this new agent uses `VertexAiCodeExecutor` to execute code within the Vertex AI Code Interpreter Extension, whereas the original sample uses `BuiltInCodeExecutor` to run code in the model's built-in sandbox.
A `README.md` file is also included to provide an overview, setup instructions, and sample usage for the new agent.
