ci: Add Bicep parameter validation workflow and script

[Harsh-Microsoft]

Purpose

This pull request introduces a new GitHub Actions workflow for validating Bicep parameter files in the repository. The workflow is designed to run automatically on a schedule, on pull requests to main and dev branches, and can also be triggered manually. It checks the integrity of Bicep parameter mappings, uploads validation results, and sends email notifications to the team based on the outcome.

The most important changes are:

New CI/CD Workflow for Bicep Parameter Validation

• Added .github/workflows/validate-bicep-params.yml to automate validation of Bicep parameter files in the infra/ directory. The workflow runs on a schedule (weekly), on pull requests to main and dev, and via manual triggers.
• The workflow uses scripts/validate_bicep_params.py to perform strict validation, outputs results to summary and artifact, and fails the workflow if errors are detected.

Notification and Reporting Enhancements

• On scheduled runs, the workflow sends an email notification using a Logic App webhook if validation fails or succeeds, including detailed results and a link to the workflow run.
• Validation results are uploaded as an artifact (infra_results.json) and retained for 30 days for audit and troubleshooting purposes.
