Docs: Fix syntax for code block within list

This commit fixes two small AsciiDoc syntax problems that prevented a
line of code from displaying properly. First, it changes the code block
lines from three dashes to four dashes. Second, it adds a plus sign on
the preceding line, to connect the code block to the previous list item.
