What's Changed

.NET versions updated

This version of VS Test upgraded .NET to net8 and net9.

We remain backwards compatible with previous versions of Microsoft.NET.Test.SDK. This change does NOT prevent you from:

• Updating to the latest VS, and running tests from net6.0 test projects.
• Updating to the latest .NET SDK, and running tests from net6.0 test projects.

It also has no impact on .NET Framework projects, where we continue targeting .NET Framework 4.6.2.
