Minor tweaks to file creation activity

[crichID]

@githubtraining/trainers my first commit ended up directly on master 😞 so this is technically the second commit on this file.

The changes included:

• Remove the first line in the activity that instructs the students to find a meme they want to caption. The meme is randomly assigned when the script creates the files.
• Add instructions for how to open files directly from the command line using Atom and VS Code.

This PR only includes some changes I made to the second bullet because I didn't want to end with code . followed by a period. You can see the other changes here: ac31865.

Question: Should we also include something to the effect of -- some additional setup may be required on your machine for these to work? Or leave it alone?

My experience working with people tells me they won't read something so subtle 🤷‍♂️

I don't think we need to identify that some setup might be required. I also agree with @hectorsector that most people will miss that subtle note. We tend to shy away from discussing configuring an editor for Git in class, so, letting them know that VS Code and Atom can be used directly from the terminal might be enough to get them to go-go-google.

looks good to me 👍

Works for me, too! I would personally add that warning note just to cover our bases, but I agree with @hectorsector and @beardofedu that it's unlikely to be read.
