Updated step 3 in the scene setup section

I'm very new to Godot, and as a good first step I have decided to follow the official docs for guidance. When I got to the Signals portion, I have followed everything as closely as possible but still ended up getting errors. Turns out step 3 was incorrect - perhaps it was correct at some point but it wasn't updated. Instead of dragging the sprite_2d.tscn on top of Node2D you needed to put it under. That cost me an hour of pulling my hair out. In the end, good folks in the Discord channel helped me figure it out. But I figured I might as well fix this so someone else who is just starting with Godot doesn't spend an hour thinking they are bad at programming.

Thanks for opening a pull request!

Unfortunately, I'm not sure if this is the right way to avoid confusion. It might be better to point users towards using the manual approach to instancing a subscene (e.g. with the chainlink icon in the Scene tree dock).

If your scene currently only has a single node, drag-and-dropping another scene or node on top is identical to drag-and-dropping it under.

The visual drag-and-drop indicator doesn't make this very clear, as it barely has any visual difference between drag-and-dropping on top of a node (which adds as a child) and below a node (which adds as a sibling). However, in scenes with only a single node, this has no difference in practice because you can't have multiple root nodes in a scene.

Also, the screenshot was made with a non-default theme and scale. Please use the default editor theme and 100% editor scale for screenshots (or downsize the screenshot in an image editor if taken at an editor scale above 100%).
