Add syntax-highlighting to fenced code-blocks

@ashmaroli Thanks for reading all articles. The latest post / article definitely has syntax highlighting, see https://github.com/planetruby/gems/blob/master/18-hexapdf.md Or am I missing something? Yes, for adding if the old articles miss the syntax highlighting. PS: By the way, thanks for your great work on jekyll. Keep it up. Cheers. Prost.

Yes. I was referring to the articles updated in the commit: 11b11ac

Likewise, thank you for all the work in curating gems and plugins in the Ruby Universe.
Highly appreciate it.

Thanks for your kind words. I see. You're right - the articles are still using the old ~~~ code block style and no syntax highlighting. I will try to update the articles over the next weeks (with the new (re)start / updates of the Gem of the Week series). Cheers. Prost. PS: You're of course invited to write-up a gem of your choice for the series :-).
