CICD workflow fix for azd deployment

[JinLee794]

This pull request refactors the Azure deployment workflow in .github/workflows/deploy-azd.yml to streamline authentication handling, modernize scripting practices, and simplify output extraction. The most significant changes are the removal of a detailed authentication status check, conversion of authentication logic to PowerShell, and updates to service endpoint extraction.

Authentication handling:

• Removed the verbose authentication status check step that provided guidance and error handling for OIDC and Service Principal authentication, simplifying the workflow and reducing output clutter.
• Refactored the Azure Developer CLI authentication logic from bash to PowerShell, improving compatibility and maintainability for Windows runners and aligning with best practices for Azure workflows.

Service endpoint extraction:

• Updated the extraction of frontend and backend URLs to use the environment variables FRONTEND_CONTAINER_APP_FQDN and BACKEND_CONTAINER_APP_FQDN instead of parsing azd show output, making the workflow more robust and less dependent on CLI output parsing.

Network whitelist management:

• Removed commented-out steps for whitelisting and cleanup of the GitHub Runner IP in Azure Storage Account network rules, reducing complexity and potential for errors in IP-based access management. [1] [2]

PowerShell string comparison should use quotes around the GitHub expression. The current syntax \"${{ steps.azure-login-oidc.outcome }}\" may not evaluate correctly in PowerShell conditional statements. Consider using -eq 'success' instead.

Same PowerShell string comparison issue as above. The GitHub expression \"${{ steps.azure-login-sp.outcome }}\" should be properly quoted or use single quotes for the comparison value.
