docs: Add read-only Python MSSQL server implementation to README

This PR adds a new Python-based MSSQL server implementation to complement the existing Node.js version. Key differences:

- Language: Python implementation vs existing Node.js implementation
- Access Mode: Read-only by design for enhanced security
- Features:
  - Configurable access controls
  - Schema inspection capabilities
  - Safe database interaction through Python ecosystem
  - Built with Python's robust database handling libraries

This implementation provides an alternative for users who prefer Python or need Python-specific database handling features while maintaining the same security standards as the original MSSQL server.
