Build/add workflow

[ChingEnLin]

This pull request introduces a comprehensive CI/CD pipeline for the QueryPal project using GitHub Actions. It adds a detailed workflow for running backend and frontend tests, performing build verification, and uploading coverage reports. Additionally, it documents the new pipeline and removes the previous Docker build and push workflow.

CI/CD Pipeline Implementation and Documentation:

• Added a new .github/workflows/ci.yml workflow that runs backend (Python) and frontend (Node.js) tests in parallel, checks code quality, uploads coverage reports to Codecov, and verifies frontend build artifacts. This workflow is triggered on pushes and pull requests to key branches.
• Added a new .github/README.md file documenting the structure, jobs, and usage of the new CI/CD pipeline, including local testing instructions and coverage details.

Cleanup of Legacy Workflows:

• Removed the old .github/workflows/docker-build-push.yml workflow, which previously handled Docker image builds and pushes to Azure Container Registry.
