This PR introduces a Dockerfile to the project, enabling Docker support for the Node.js application. By containerizing the application, we ensure a consistent environment across development, testing, and production.
Fixes #11
Changes:
1.) Added a Dockerfile that uses the node:20-alpine base image for a minimal image size and faster build times.
2.) Installed project dependencies inside the container.
3.) Exposed port 3000 for the application to run inside the container.
4.) Configured the container to run npm start to launch the app.
