Completion is incorrect for lambda parameters

[333fred]

using System;

namespace ConsoleApp2
{
    class Program
    {
        static void Main(string[] args)
        {
            Test(prog => prog.[||]); // Invoke completion on prog.
        }

        static void Test(Action<Program> d)
        {
        }
    }
}

Invoking completion here brings up the members of Action<Program>, not the members of Program, rendering completion completely useless. cc @ivanbasov.

Likely a dup of #35027

Should be fixed with #35067 but I will double check.

Verified. Fixed with #35067
