Added logo sprite property so we can access the logo to be moved on the screen

MainScene.cs

using Godot;

namespace QuickStart.Core.Scripts
{
    public class MainScene : Node2D
    {
        private Sprite _logo;
        public override void _Ready()
        {
            _logo = GetNode<Sprite>("Logo");
            GD.Print("Hello IdiotCoder.com");
        }
    }
}
