Fix code highlighting

[rdwatters]

Not sure what "```golang" is supposed to trigger

https://github.com/gohugoio/gohugoioTheme/blob/master/src/js/hljs.js#L14

There are aliases hugo and golang set up for go. This was partially from the previous site's content and partially from the last design, which included icons at the top right of each copyable code block to denote the file format.

I can modify all code blocks to use html, but colors and js should be an issue in the Hugo theme repo. I'll open an issue there.

@rdwatters if it is html it should be changed in the source (i.e. the content files in this repo), but does not solve the real problem: I have tested with both html and golang and it still doesn't look good. So it would be good to address the real problem and not just one of the less important bullet points in the list above.

[bep]

Just to be clear: Keep the golang tagging. This has to be fixed in the highlight.js definition/config, if possible; I will see if I understand it.

The variances are due to the way they are designated in the content. The style is subjective and can be chosen here: https://highlightjs.org/static/demo/ if you prefer to pick one out yourself.

[bep]

@budparr you are replying to these issues as you would to random people from a third support line.

Let me rephrase:

The code highlighting, esp. for the custom golang language definition, looks like crap, and should be fixed.

[budparr]

Apologies, @bep. Wasn't my intent, just a bit of hit-and-run on my part for time-sake. There's an issue for making the content more consistent here: gohugoio/gohugoioTheme#50

And because you didn't like the color scheme I chose—which I chose to be Hugo-like— I thought you might want to choose one yourself.

[bep]

Let us handle this in #50

[bep]

This has nothing to do with the colour scheme. Or very little, but I will fix it now that I have an actual working dev environment.

[rdwatters]

but does not solve the real problem

Right. That's why I opened up the other issue. As for the language designation, I always think it's worth making content consistent, and it's just a quick find and replace anyways. I can do golang if that's what you want. I'll submit a PR this afternoon.
