Fix MCP server documentation to reference correct entry point

Update all documentation references from graphiti_mcp_server.py to main.py.
The old filename was causing "No such file or directory" errors when users
tried to run the commands as documented. The actual entry point is main.py
in the mcp_server directory.

Changes:
- Update 7 command examples in README.md
- Update example configuration file with correct path
