Add copy icon to code blocks

[mikkelhegn]

Code blocks do not have a copy icon, so you can easily copy the whole content to your clipboard to quickly paste it into a terminal.

The code block is also not aligned on the right margin with the paragraphs.

@mikkelhegn Do we want to keep this issue open due to the alignment of the code blocks?

[mikkelhegn]

Yeah - I think we should fix that as well.

[mikkelhegn]

I'm seeing this on a code block which it does not make sense to be able to copy. Is there any way we can control this?
