ci: update image tag to latest_waf

[Harsh-Microsoft]

Purpose

This pull request updates the default Docker image tag used throughout the deployment process from latest or latest_fdp to latest_waf. This change ensures consistency across documentation, configuration files, deployment templates, and CI/CD workflows, aligning the default image tag with the new naming convention.

Deployment and Configuration Updates:

• Updated the default backend and frontend container image tags to latest_waf in infra/main.bicep, infra/main.parameters.json, and infra/main.waf.parameters.json to standardize deployments on the new image tag. [1] [2] [3] [4]

CI/CD Workflow Adjustments:

• Modified the tag determination logic in .github/workflows/deploy-KMGeneric.yml and .github/workflows/docker-build.yml to use latest_waf instead of latest_fdp for the main branch, ensuring that builds and deployments use the new tag by default. [1] [2]

Documentation Updates:

• Updated documentation in documents/CustomizingAzdParameters.md and documents/DeploymentGuide.md to reflect latest_waf as the default and recommended image tag, replacing references to latest and clarifying example values. [1] [2]
