Bug fix: Fix the Git Service when running on Ollama

[esnible]

Summary

We supply a configuration for the Git Service when running on Kagenti under Ollama, but it doesn't work.

For example, the chat query What do you think about https://github.com/kagenti/agent-examples/issues/218 ? yields

Thought: The user query involves retrieving issues from a specific GitHub repository and issue number. Action: list_issues Action Input: {"owner":"kagenti","repo":"agent-examples","state":"all"}

The default port for an MCP tool in Kagenti is 8000, but this Agent example assumes the MCP server will be deployed on 9090.
