Amazon Bedrock AgentCore Samples - [Bug]

**Describe the bug**
A clear and concise description of what the bug is. This could be anything from:

1. A typo or text changes that make the lab better.... to
2. minor annoying code that still works.. to
3. breaking changes

**To Reproduce**
Steps to reproduce the behavior (or some version of this):
1. Go to '01-tutorials/01-AgentCore-runtime/02-hosting-MCP-server/hosting_mcp_server.ipynb'
2. Scroll down to 'Creating Local testing Client'
3. Go to streamablehttp_client(mcp_url, headers, timeout=120, terminate_on_close=False)

**Expected behavior**
`with streamablehttp_client does not support timeout=120, `
change to
`with streamablehttp_client(mcp_url, headers, terminate_on_close=False)`

**Screenshots**
Error:

```
