improve image in the doc word context

First of all thank you for this great workshop tutorial!! 🚀

In the context of wording used in the current tutorial:

Set the value to Tensorflow with Cuda and Python 3.9 (UBI 9)

I know one should read the manual, but I'm always preferring to look at the pictures (like a child 😅 ) and as I've run the pipelines I was met with the error of keras not found... which ultimately I did not set the pipeline file in the editor according to the text, but according to the image ...embarassing I know.

This PR proposed "a more explicit figure" so that people looking at either text or just the picture, won't miss it:

ie: if looking at the pictures and overlooking the text, would bump into

Exception encountered at "In [2]":

@cfchase I undestand I can ask for your review and if positive merge, please?

As noted in original message, thank you for this great workshop tutorial!! 🚀

While I like it, I'm not sure if it's worth doing a more complex picture that will take more work to replace with newer screenshots. @MelissaFlinn @erwangranger opinions?

[erwangranger]

i'd say, merge it in as-is and we can re-simplify the screenshot next time we need to update it. I think a lot of people might run into this tomorrow, so it'd be nice to have fixed now.
