Update NuGet Packages

[Trenly]

📖 Description

Updates NuGet package versions in src\Directory.Packages.props to newer supported releases. These updates move the repository onto current package baselines that include accumulated servicing fixes, improve compatibility with newer .NET/runtime toolchains, and reduce long-term maintenance risk from version drift.

Why This Helps

• Aligns key dependencies with actively serviced versions used by current SDK/tooling
• Brings upstream bug fixes from package lines, including reliability fixes in test discovery/execution stacks and runtime/library servicing fixes delivered through newer .NET package trains
• Improves test framework coverage by upgrading NUnit (3.12.0 → 4.6.1), NUnit3TestAdapter (3.15.1 → 6.2.0), and xunit (2.4.2 → 2.9.3) to modern versions
• Maintains healthier security posture by updating transitive dependencies

🔒 Security Improvements

Updated packages include security fixes from:

• Microsoft.ApplicationInsights 3.1.2 (includes OpenTelemetry security advisory fixes)
• Microsoft.Extensions.Hosting 10.0.8 (carries .NET 10.0.8 servicing releases with security fixes)
• System.Text.Json 10.0.8 (aligned with .NET 10.0.8 servicing)

📝 Additional Changes

• Added System.Text.Json package reference to src\WinGetUtilInterop.UnitTests\WinGetUtilInterop.UnitTests.csproj

Things I didn't comment on are probably fine / will have little to no changes required to build. The comments are probably all deserving of their own PR due to the additional changes needed.
