Add Dockerfile for Docker containerization

Description

This pull request introduces a Dockerfile to the project, which allows for building a Docker image and running the application inside a container.

Changes

• Added Dockerfile in the root directory with instructions for building the Docker image.
• Updated README.md with instructions on how to build and run the Docker image.

Benefits

• Consistent Environments: Docker containers provide a consistent and reproducible environment for running the application, reducing the risk of "works on my machine" issues.
• Portability: The Docker image can be easily shared and deployed across different environments (development, staging, production) without worrying about dependencies or system configurations.
• Isolation: Each Docker container runs in an isolated environment, reducing conflicts between applications or libraries.
• Scalability: Docker containers make it easier to scale and distribute applications across multiple hosts or a cluster.
