Remove prefixed $ from shell command examples

[larouxn]

As the prefixed $ makes it impossible to copy and paste example shell commands, I was thinking it might be beneficial to remove them from the README. What do y'all think?

We did a very similar thing for one of our internal docs so I think this change makes total sense 👍
Just in case let's wait for someone else's opinion

Yep, LGTM!

I don't know because while it makes copying more easy with triple-click selection, it also makes it less clear that these are commands to type at the shell prompt… Also it's the default from bundler generated gems for instance, so I don't think people are too confused:

I suppose it is a bit less clear they are shell commands but I feel it's still somewhat clear given the code block formatting and usage of terms like bin/rails. As for Bundler's default, a bit brazen, but I feel Bundler should update their docs/generation as well then. Ever since GitHub added this copy button, having breaking $ prefixed has become a bit of an issue.

re: triple click, this is the current experience. Can't do much with $ gem install rails. 🤷‍♂️

I don't think this change makes things more clear. Perhaps 20% less clear but 100% more convenient. 😅

Yes that's what I meant by triple-clicking, this PR makes it much more useful. The copy button is similar in that regard. Ok I'm convinced!

While we're at it, can we change all the bash into sh-session?

Sure thing. Done!

(feel free to merge this if it looks good on your end)
