Does not resolve references to zero

[dbanksdesign]

Scenario:
If a design token/style property has a value of 0 (a number, not a string) and you have a reference/alias to that value, when you build Style Dictionary says the reference doesn't exist.

Here is a quick test:

const StyleDictionary = require('style-dictionary');

StyleDictionary.extend({
  properties: {
    test: { value: "{zero.value}" },
    zero: { value: 0 }
  },
  platforms: {
    css: {
      transformGroup: 'web',
      files: [{
        destination: "test.css",
        format: "css/variables"
      }]
    }
  }
}).buildAllPlatforms();
