Move application to Docker image

This commit moves the application to a Docker image to streamline the deployment process. By utilizing a Docker image, the application can be easily packaged and distributed across different environments, ensuring consistency and ease of deployment. The changes include: - Added .dockerignore file to specify files to be excluded from the Docker build - Modified .github/workflows/release.yml to build the application using Docker - Updated the Dockerfile to include necessary dependencies and instructions for building the application within the Docker image - Adjusted the Makefile to reference files within the Docker image for building the application
