[Bug]: Parsing error for tokens with number in name if outputReferences: true

[nuke-ellington]

What happened?

The following input will result in broken output. This happens only if there is the same number (in this case 1) in both a token name as well as a nested value.

{
    "shadow-1-x-offset-1": {
      "value": "0",
      "type": "number"
    },
    "shadow-1-y-offset-1": {
      "value": "1", // Changing this to any number other than 1 will result in valid CSS
      "type": "number"
    },
    "shadow-1-blur-1": {
      "value": "2",
      "type": "number"
    },
    "shadow-1-spread-1": {
      "value": "0",
      "type": "number"
    },
    "shadow-1": {
      "value": [
        {
          "x": "{shadow-1-x-offset-1}",
          "y": "{shadow-1-y-offset-1}",
          "blur": "{shadow-1-blur-1}",
          "spread": "{shadow-1-spread-1}",
          "color": "#FFF",
          "type": "dropShadow"
         }
      ],
      "type": "boxShadow"
    }
}

Reproduction

Config:

{
  "source": [
    "studio.json"
  ],
  "log": {
    "verbosity": "default"
  },
  "preprocessors": [
    "tokens-studio"
  ],
  "platforms": {
    "css": {
      "transformGroup": "tokens-studio",
      "transforms": [
        "name/kebab"
      ],
      "buildPath": "build/css/",
      "files": [
        {
          "destination": "_variables.css",
          "format": "css/variables"
        }
      ],
      "options": {
        "outputReferences": true
      }
    }
  }
}

Broken output:

:root {
  --shadow-1-x-offset-1: 0;
  --shadow-1-y-offset-1: 1;
  --shadow-1-blur-1: 2;
  --shadow-1-spread-1: 0;
  --shadow-1: var(--shadow-var(--shadow-1-y-offset-1)-spread-1) 1px var(--shadow-1-blur-1)px var(--shadow-1-x-offset-1) #fff;
}

Expected output

--shadow-1: var(--shadow-1-spread-1) var(--shadow-1-x-offset-1) var(--shadow-1-blur-1)px var(--shadow-1-y-offset-1) #fff;

Version

1.3.0 (A quick test with 2.0.0 lead to same results)
