chore: Bicep Parameter validation email format change

[NirajC-Microsoft]

Purpose

This pull request enhances the Bicep parameter validation workflow by introducing structured HTML email reporting, updating parameter naming for clarity and consistency, and improving the notification process. The main themes are improved reporting and parameter standardization.

Key changes:

1. Enhanced Reporting & Notifications

• Added HTML email report generation to scripts/validate_bicep_params.py, including a new generate_html_report function and CLI options for HTML output, accelerator name, and workflow run URL. This provides a more readable and professional notification format. [1] [2] [3]
• Updated the GitHub Actions workflow (.github/workflows/validate-bicep-params.yml) to generate and attach the HTML report, and to use its contents in notification emails instead of plain text. This change improves the clarity and presentation of validation results sent to the team. [1] [2] [3]

2. Parameter Naming Consistency

• Standardized and clarified parameter names in infra/main.parameters.json and infra/main.waf.parameters.json. For example, replaced containerRegistryEndpoint with containerRegistryHost, and grouped AI-related parameters under a consistent ai* prefix. This improves maintainability and reduces confusion. [1] [2]

3. Environment Variable Alignment

• Updated parameter value substitutions to match new environment variable names, such as changing ${AZURE_ENV_IMAGE_TAG} to ${AZURE_ENV_IMAGETAG} and ${AZURE_ENV_EXISTING_LOG_ANALYTICS_WORKSPACE_RID} to ${AZURE_ENV_LOG_ANALYTICS_WORKSPACE_ID} for consistency across the deployment process. [1] [2]
