update the script for making labs from lab keys

[carriewright11]

in PR #176 I updated the R script for making labs from the lab keys to ignore the RStudio lab, because the use case doesn't align as well.

• currently want people to change things in a chunk, so it would be nice if the key showed the change
• want people to learn how to add chunks, the blank empty chunks make that kinda odd
• people got confused by the empty chunks last time because they aren't as response -like as the other labs

maybe we can update the script to instead of ignore the RStudio lab, it only copies the text and ignores the chunks or something?

hmmm actually that would also mess up the extra header that I add in the key - but maybe we could have it ignore that

if you just put {r} instead of {r 1.1response} it will ignore the chunk!

[carriewright11]

hmmm it will still make the new header...

Just tried this.. and the answer of creating a new chunk shows like the chunks that have code in them like the initial installing packages, which is what I thought would happen but not actually what I want... also shows the answer for the new header. I think it might be best to revert all those changes and going back to not rendering the lab from the key? Maybe we can come up with a better solution though later.
