Syntax Highlighting Infinite Loops

[jswrenn]

Bug Report

I've encountered a few instances where attempting to highlight semi-valid syntax fragments causes zola build to never terminate.

Environment

Zola version: 0.11.0

Expected Behavior

The build should complete, although the snippet might be mis-highlighted.

Current Behavior

The build doesn't terminate.

Step to reproduce

This snippet was the latest one to trigger the problem for me:

```javascript
{
  ...

  /* 30 - 14 = 16 seats taken  */
  "seats": "<strong>Maximum Enrollment:</strong> <span class=\"seats_max\">30</span> / <strong>Seats Avail:</strong> <span class=\"seats_avail\">14</span>",
  /* 10 + 5 + 1 = 16 seats taken */
  "regdemog_json": "{\"FY\":10,\"So\":5,\"Oth\":1}",
  /* 16 seats taken */
  "regdemog_html": "<p class=\"enroll_demog\">Current enrollment: 16</p><div class=\"demogchart\"></div><div class=\"demogchartlegend\"><ul><li class=\"pieitem item_fy\">62.50% - First Year</li><li class=\"pieitem item_so\">31.25% - Sophomore</li><li class=\"pieitem item_oth\">6.25% - Other</li></ul></div>"

  ...
}
```

There's an issue with the js syntax, try to use the ts instead.

I got bitten by the same problem: Zola hangs (infinite loop) when there is a JSON code block labeled as JavaScript. It's going through when annotated with ts or json instead.

I'll try to update the JS syntax for the next release since it seems to be main culprit :/

Should be fixed now
