RCS1250 Does not offer 'Simplify Object Creation' for IAsyncEnumerable<>

[John-Leitch]

RCS1250 is not offered in the following case:

namespace Foo;

internal class Program
{
    private static string[] _test = ["foo", "bar"];

    private record TestRecord(string Test);

    private static async System.Collections.Generic.IAsyncEnumerable<TestRecord> TestAsync()
    {
        foreach (var test in _test)
        {
            yield return new [|TestRecord|](test);
        }
    }

    private static void Main(string[] args)
    {
        Console.WriteLine("Hello, World!");
    }
}
