chore: Bicep Parameter validation email format change

[NirajC-Microsoft]

Purpose

This pull request enhances the Bicep parameter validation workflow by adding support for a structured HTML email report and improving notification handling. The main improvements include generating a detailed HTML report for validation results, updating the workflow to use this HTML output for email notifications, and refactoring the notification logic for clarity and maintainability.

HTML Email Reporting:

• Added a new generate_html_report function in validate_bicep_params.py to create a structured, Outlook-compatible HTML report summarizing validation results, including error and warning counts, per-file details, and workflow run links.
• Introduced new CLI arguments (--html-output, --accelerator-name, --run-url) to allow the script to generate and save the HTML report with contextual information.

Workflow and Notification Improvements:

• Updated the GitHub Actions workflow (.github/workflows/validate-bicep-params.yml) to:
  • Generate the HTML report during validation and upload it as an artifact. [1] [2]
  • Use the HTML report as the body for both failure and success notification emails, replacing the previous plain text approach. [1] [2]

Code Integration:

• Integrated HTML report generation into the main validation script, ensuring the report is written alongside the JSON output when requested.

These changes provide more readable, actionable, and visually appealing validation notifications for the team.
