* feat: Add pgvector tutorial with PostgreSQL integration

It includes Docker setup instructions, feature definitions, sample data generation, and vector similarity search functionality. Key files added are `docker-compose.yml`, `example_repo.py`, `feature_store.yaml`, `pgvector_example.py`, `README.md`, and an initialization SQL script for pgvector.
