Prettier Liquid: case, when

[charlespwd]

https://shopify.dev/api/liquid/tags#case

• case is easy: it's just a LiquidExpression
• when is trickier
  • https://github.com/Shopify/liquid/blob/fix/range-weird-type-handling/test/integration/tags/standard_tag_test.rb#L186-L199 suggests the syntax is really
    nonEmptyListOf<liquidExpression, (space* ("or" | ",") ~identifier space*)

{% # printWidth: 1 %}
{% case candy.type %}
  {% when "nerds",
    "skittles",
    "gummy bears"
  %}
    yum!
  {% else %}
    ok!
{% endcase %}

Decisions:

• Go with the established break on second arg, after comma
• Replace "or" with ","
