Deleted all $ signs in code blocks in the "Composing multiple nodes in a single process" tutorial

[Trimple]

$ signs prevent from effective use of "copy to clipboard" button. Previous tutorials don't have them in code blocks

So I agree with you that having the $ in here makes it not copy-n-pastable.

But the reason we left it like this on this tutorial is that these are really snippets showing a command and the result, not just a copy-n-paste command. We can definitely make this copyable, but if we are going to do that, we should split the result into a separate code-block, as you don't want to paste those into the terminal.

True, I think for the command results together with commands it makes sense. But it is not needed in the code blocks with only commands. If it won't affect a document stile too much I can put back $ for every code block with result and leave code blocks with only commands without $ signs.

We can think about the commands with results as console snapshots. Therefore $ is needed.

The problem is that you then have this inconsistent state within the page where some blocks are copyable and some are not. I'd rather have them all be consistent within the page, one way or the other. Given what most of our other pages do, I think we should probably split them into separate command and result blocks across the board.

I updated the file and squashed the commits. Can you please take another look?
