Upgrade project to .NET 10 GA release

[qodo-free-for-open-source-projects]

Description

• The project was using .NET 10 preview versions with preview package dependencies that need to be updated to stable GA releases
• CI/CD workflows were configured for preview versions and need to be updated to use GA versions and latest action versions
• Conditional package references for System.Linq.Async were required for preview versions but need to be replaced with the stable System.Linq.AsyncEnumerable package for .NET 10 GA

Deliverables

• Update packages: Upgrade Microsoft.Extensions and Microsoft.TestHost from preview RC versions to stable 10.0.0 GA versions
• Update workflows: Migrate CI/CD pipelines from .NET 10 preview to GA, update action versions to latest stable releases
• Replace dependencies: Remove conditional System.Linq.Async references and use System.Linq.AsyncEnumerable for .NET 10 compatibility
• Fix documentation: Update XML documentation tags to align with .NET 10 standards
