[LiquidDoc] Lone single quote in comment breaks plugin

[davidwarrington]

{% comment %}
  There's a non-breaking single quote in this line

  Accepts:
  - update_url: {Boolean} There's a breaking single quote here

  Usage:
  {% render 'product-variant-picker', product: product %}
{% endcomment %}

In the above example the first single quote after LiquidDoc begins appears to be detected as opening a string. The syntax highlighting breaks, and after the comment I no longer get autocompletions. A single quote in a word before Accept: seems to be ignored as expected.

I found this in the product-variant-picker snippet in Dawn.

Should maybe make some action on in previous chats pertaining to Liquid docs. Will patch in meantime.
