Tweak GoNotes.adoc formatting
Hi Eric,
I chose :source-highlighter: prettify
because it does not require any extra build requirements (e.g. rouge), and it supports Go unlike the default minimal highlightjs highlighter that Asciidoctor loads.
Other changes including checking sample code indentation with gofmt (play.golang.org), adding link to Go issue #19412, and list item continuation (+) in the "Catchable exceptions require silly contortions" section.
Please double check. Hope I didn't mess anything up. Many thanks!
By the way, that is an amazing report that you wrote. Thank you for sharing your Python-to-Go migration experience with us!
