fix: merging dev changes to main branch

[Roopan-Microsoft]

Purpose

• This pull request includes several changes to the CI/CD workflow, Docker configuration, and frontend testing setup. The most important changes involve updates to the GitHub Actions workflow for building and pushing Docker images, enhancements to the Dockerfile, and the addition of mock files for frontend testing.

CI/CD Workflow Improvements:

• .github/workflows/docker-build-and-push.yml: Updated the workflow to trigger on multiple events and branches, added steps to determine the Docker image tag based on the branch, and simplified the build and push process using the docker/build-push-action. [1] [2]

Docker Configuration Enhancements:

• WebApp.Dockerfile: Added installation of development dependencies @types/node and @types/jest to the Docker image.

Frontend Testing Setup:

• frontend/__mocks__/dompurify.ts: Added a mock implementation for DOMPurify to return the input string, facilitating testing.
• frontend/__mocks__/fileMock.ts: Added a mock file to represent file imports during testing.

Does this introduce a breaking change?

• Yes
• No

Golden Path Validation

• I have tested the primary workflows (the "golden path") to ensure they function correctly without errors.

Deployment Validation

• I have validated the deployment process successfully and all services are running as expected with this change.

What to Check

Verify that the following are valid

• I have built and tested the code locally and in a deployed app
• For frontend changes, I have pulled the latest code from main, built the frontend, and committed all static files.
• This is a change for all users of this app. No code or asset is specific to my use case or my organization.
