Pull request overview

This PR adds Windows platform support to four PowerShell scripts used for building, deploying, and testing .NET MAUI applications. The changes enable these scripts to handle Windows as a target platform alongside existing support for Android, iOS, and MacCatalyst.

Changes:

• Added "windows" to ValidateSet for Platform parameters across all four scripts
• Implemented Windows-specific build and deployment logic (similar to MacCatalyst approach)
• Updated documentation (synopsis, descriptions, examples) to include Windows platform
• Added PR number auto-detection and markdown reporting features to verify-tests-fail.ps1
