Improve Docker build process and CI workflow

Referred Issue - #66

Description

I introduced several changes to optimize the Docker build process, enhance the CI workflow, and improve overall project consistency.

Changes made:

1. Modified Dockerfile:

   • Optimized the build process for better consistency and reliability.
   • Updated dependency installation and pruning steps.

2. Updated .github/workflows/ci.yml:

   • Added steps in the CI workflow to incorporate Docker build and run tests.

3. Modified package.json:

   • Added new scripts related to Docker testing.
   • Updated dependencies or scripts as needed for the new Docker workflow.

4. Added .dockerignore:

   • Created a new .dockerignore file to exclude unnecessary files from the Docker build context, optimizing build time and image size

5. Added test-docker.sh:

   • Created a new shell script to automate Docker build and run tests.

Testing

I have tested these changes locally. The Docker image builds successfully, and the new test script runs without errors. The updated CI workflow has been verified to work as expected.
