Amazon Bedrock AgentCore Samples - mcp client timeout seconds

**Describe the bug**

In https://github.com/awslabs/amazon-bedrock-agentcore-samples/blob/main/01-tutorials/01-AgentCore-runtime/02-hosting-MCP-server/hosting_mcp_server.ipynb, the timeout int 120 is not a valid parameter when creating the MCP client.

AttributeError: 'int' object has no attribute 'seconds'

in:
async with streamablehttp_client(mcp_url, headers, timeout=120, terminate_on_close=False) as (

This works when removing the timeout input parameter.

**To Reproduce**
Run jupyter lab agentcore/amazon-bedrock-agentcore-samples/01-tutorials/01-AgentCore-runtime/02-hosting-MCP-server/hosting_mcp_server.ipynb

Running mcp 1.8.0 on Sagemaker.
Linux default 5.10.238-231.953.amzn2.x86_64 #1 SMP Tue Jun 17 10:30:46 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

Open 01-tutorials/01-AgentCore-runtime/02-hosting-MCP-server/hosting_mcp_server.ipynb and inspect the streamablehttp_client call using timeout=120. Run the notebook in Jupyter Lab on SageMaker with mcp 1.8.0 to reproduce the AttributeError. Done means the MCP client timeout configuration no longer raises this error and the notebook runs successfully.
