Amazon Bedrock AgentCore Samples - [Bug] hosting MCP server

**Describe the bug**
01-tutorials/01-AgentCore-runtime/02-hosting-MCP-server/requirements.txt specifies mcp==1.8 but mcp v 1.8 cannot take an integer timeout value for an async http connection. Fix suggested by @EashanKaushik is to use the latest version of the library (which was *much* simpler than Claude's recommended fix :-)

**To Reproduce**
Run hosting_mcp_server.ipynb, cell python invoke_mcp_tools.py will fail.

**Expected behavior**
A clear and concise description of what you expected to happen.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**! Additional context !**
- Sagemaker Studio Kernel used
- Instance used
- commit link to the workshop if you're not using the latest

Start with 01-tutorials/01-AgentCore-runtime/02-hosting-MCP-server/requirements.txt and compare the pinned mcp version with the latest compatible release. Run hosting_mcp_server.ipynb and inspect the python invoke_mcp_tools.py cell, where the async HTTP timeout failure occurs. Done means the cell runs successfully with the updated dependency.
