warpsql/docker-compose: Added pgwatch2 service

1. Added pgwatch2 service to the Docker Compose file.
2. Configured pgwatch2 to use the cybertec/pgwatch2-postgres:latest image.
3. Exposed port 3000 for the pgwatch2 service.
4. Set up PW2_ADHOC_CONN_STR environment variable for pgwatch2 to connect to the timescaledb service.
5. Configured pgwatch2 to restart automatically in case of failure.
6. Added timescaledb as a dependency for pgwatch2 to ensure timescaledb starts before pgwatch2.

Fixes: #52
