Refactor to use Microsoft.Build

[MichielOda]

This pull request introduces several important changes to the project, focusing on dependency management, build/test infrastructure, and codebase modernization. The main updates include centralizing and updating NuGet package management, refactoring project references to use newer packages, and updating the CI/CD workflow for improved compatibility and maintainability.

Dependency and Package Management:

• Added Directory.Build.props, Directory.Packages.props, and NuGet.config for central and modern NuGet package management, specifying versions and controlling asset flow. [1] [2] [3]
• Updated .github/dependabot.yml to ignore Microsoft.Build for automated dependency updates.

Build and CI/CD Pipeline Updates:

• Refactored .github/workflows/release.yml to remove Ubuntu test jobs, update action versions, and switch to a new reusable workflow with improved parameter naming and additional build/test options.

Project Reference and Code Modernization:

• Replaced all references to Skyline.DataMiner.CICD.Parsers.Common.VisualStudio.Projects with Skyline.DataMiner.CICD.Assemblers.Common.VisualStudio.Projects across the codebase for improved compatibility and maintainability. [1] [2] [3] [4] [5] [6] [7] [8]
• Updated logic in DmappCreation.cs and PublishToCatalog.cs to default to DataMinerProjectType.Unknown if conversion fails, improving error handling. [1] [2]

Testing Improvements:

• Upgraded SdkTests.csproj to use the latest MSTest SDK, centralized package versions, and added a manual test class for debugging. [1] [2] [3]
• Added minimal MSBuild files to test files and improved test categorization and reliability. [1] [2] [3] [4]

Packaging and Metadata:

• Updated Sdk.csproj to modernize package metadata, adjust output paths, and clean up package references, aligning with new central package management.

These changes collectively improve the project's maintainability, build reliability, and compatibility with modern .NET development practices.
