Using string interpolated variables in twind.config.ts breaks some functionality

[kveeti]

This config will break plugin intellisense:

import { blue } from "twind/colors";

const config: Configuration = {
  mode: "strict",
  theme: {
    extend: {
      boxShadow: {
        test: `0 0 0 4px ${blue[400]}`,
      },
    },
  },
  plugins: {
    btn: `
      bg-blue-700
      hover:shadow-test
      p-3
      rounded-md
      text-white
      transition-shadow
    `,
  },
};

If the test boxShadow is changed to

boxShadow: {
  test: `0 0 0 4px blue`,
}, 

plugin intellisense starts working again.

Even when the intellisense thinks something's wrong, the shadow will have the right color. And it doesn't matter if the shadow is used in any plugin, as long as it's in the config, it breaks the intellisense.
