dotnet test treating xunit skipped tests as failures

[zivkan]

Describe the bug

Using 9.0.100-rc.2.24474.11, dotnet test is reporting an error, and the error messages show xunit skipped tests.

To Reproduce

Unfortunately, I don't know a minimal repro, but hopefully this isn't too hard to reproduce:

git clone https://github.com/NuGet/NuGet.Client
cd NuGet.Client
dotnet test .\test\NuGet.Core.Tests\NuGet.ProjectModel.Test\

Exceptions (if any)
