Docker Setup for Django Backend and PostgreSQL Database

• Added backend.Dockerfile to containerize the Django backend application. This Dockerfile installs the required dependencies and runs the Django development server on port 8000.

Configured docker-compose.yml to define two services:

• db: PostgreSQL database configured with environment variables loaded from a .env file, and persistent storage using a named volume (pg_data)
• backend: Django backend service that depends on the database, exposes port 8000 for accessing the app, and mounts the project directory for live code updates

Also added instructions in the readme file!
