Strip prompts from copied shell scripts.

Hi Josh,

Thank you for the suggestion! We've decided to keep the dollar signs in the scripts for now. However, we would like to proceed with @bolotskydev's idea about omitting them when copying. I'm creating a separate issue for that.

Closing this PR without merging. With that said, I'd like to thank you again for the excellent contribution. It definitely got us thinking through the UX.

Best,
Simme

I think you are most suited to decide the best path forward, @bolotskydev, so I'm happy to leave this in your hands.
