New Assert.DoesNotContain overloads break compilation if LangVersion=latest is not specified

[avivanoff]

Describe the bug

Assert.DoesNotContain overloads introduced in 4.4.0 break compilation when targeting anything but net10.0 if LangVersion=latest is not specified.
The same setup works with 4.3.3.

Version used

4.4.0

Steps To Reproduce

1. Create MSTest.Sdk project.
2. Change SDK version to 4.4.0.
3. Change TargetFramework to net8.0.
4. Comment out/delete LangVersion from the project.
5. Build the project.

Expected behavior

Project builds with no error.

Actual behavior

Build is broken:

error CS0121: The call is ambiguous between the following methods or properties: 'Microsoft.VisualStudio.TestTools.UnitTesting.Assert.DoesNotContain<T>(T, System.Collections.Generic.IEnumerable<T>, string?, string, string)' and 'Microsoft.VisualStudio.TestTools.UnitTesting.Assert.DoesNotContain<T>(T, System.Span<T>, string?, string, string)'

Sample project.

Thanks avivanoff! This is indeed a regression caused by adding a new overload (span). Older versions of the compiler are confused for arrays while new versions are good. We will provide a targeted fix.
