Attachment: None value unavailable in the list for flex property

Steps to reproduce:

1. Open the inspector (F12);
2. set a flex property on a element;
3. try to chose "none" value.

Actual results:

It appears that devtools/shared/css/generated/properties-db.js provides the information of what values are suggested. The values section for flex is missing "none."

  "flex": {
///...
    "values": [
      "-moz-available",
      "-moz-fit-content",
      "auto",
      "content",
      "fit-content",
      "inherit",
      "initial",
      "max-content",
      "min-content",
      "revert",
      "unset"
    ]
  },

Looking at the most recent change to this generated file it appears that this might require some cpp or rust changes in servo/components/style/values?

I'm out of my depth at this point, I hope this research helps though
