Adding short clarification on "Hands-on: Run workflow"

I thought it could improve the first step explanation, mentioning after line an addition and a screenshot because the next one shows configuring scatterplot settings not where they are. I would like to add this line:

> - The central panel will change to allow you to configure and launch the workflow.
**_To do that choose the menu "expand to full workflow form"_**
Here is this part in the tutorial:

Does it look better?

Open topics/introduction/tutorials/galaxy-intro-101-everyone/tutorial.md at the linked section around line 668 and review the first step alongside the following screenshot. Add the proposed clarification and screenshot if it improves the explanation of how to open the full workflow form; done means the tutorial clearly directs readers to that menu before configuring scatterplot settings.
