This PR addresses an issue where running the examples/helloworld example results in a streaming-related error. The changes ensure a smoother developer experience when executing the helloworld example by:

1. Enabling Streaming Mode in Agent Card: Updated the Agent Card in the examples/helloworld directory to explicitly enable streaming mode, resolving the error encountered during execution.
2. Adding Comments in Test Client: Added clarifying comments to the test_client.py script to guide developers on the expected behavior and configuration when running the helloworld example.
