[BUG] Warning about nullable despite Nunit.Analyzers

[eraserix]

Describe the Issue

In a unit test class that sets up members during "[SetUp]", VS Code displays the warning CS8618 (must contain non-null value). The code works as expected (dotnet format, dotnet test). Rider does not show this warning for the same test class.

Steps To Reproduce

1. Add a field with an object inside a test class
2. Add reference to Nunit analyzers through Directory.Packages.props, Directory.Test.props
3. Initialize the field inside the [SetUp] Method.

Expected Behavior

The Nunit.Analyzers contain a suppressor rule that should suppress that warning about null if field is initialized in [SetUp].
