Detect ReturnsForAnyArgs/ReceivedWithAnyArgs simplification with "default(!)"

[rklec]

Could you detect and suggest the simplification of ...Any calls with default for modern C# versions, as you describe here?

public interface ITest
{
    void DoSomething(string? thing);
}

public class Test
{
    [Test]
    public void TestSth()
    {

        var test = Substitute.For<ITest>();

        test.DoSomething("this");

        test.ReceivedWithAnyArgs().DoSomething(Arg.Any<string>()); // too complicated
        test.ReceivedWithAnyArgs().DoSomething(default!); // could be simplified as this
    }
}

...the same for setting return args with ReturnsForAnyArgs etc.
