build(docker): add Docker support and GitHub Actions workflow for Doc…

…ker image publishing

Add a `.dockerignore` file to exclude unnecessary files from the Docker build context, reducing image size and build time. Introduce a `Dockerfile` to define the Docker image for the application, using Node.js 18-alpine for a lightweight base image. The Dockerfile installs dependencies, builds the application, and sets the command to start the app.

Create a GitHub Actions workflow (`docker-publish.yml`) to automate the building and publishing of Docker images to the GitHub Container Registry. The workflow triggers on new tags, builds the Docker image, and pushes it with both `latest` and version-specific tags. This setup streamlines the deployment process and ensures consistent and reproducible builds.
