Require to have a postcss.config.js file on build

[IzioDev]

Here is my rollup.config:

import typescript from "rollup-plugin-typescript2";
import peerDepsExternal from "rollup-plugin-peer-deps-external";
import commonjs from "@rollup/plugin-commonjs";
import resolve from "@rollup/plugin-node-resolve";
import scss from "rollup-plugin-scss";
import json from "@rollup/plugin-json";
import tailwind from "rollup-plugin-tailwindcss";
import packageJson from "./package.json";

export default {
  input: "src/index.ts",
  output: [
    {
      file: packageJson.main,
      format: "cjs",
      sourcemap: true,
    },
    {
      file: packageJson.module,
      format: "esm",
      sourcemap: true,
    },
  ],
  plugins: [
    peerDepsExternal(),
    tailwind({
      input: "./src/styles.css",
      purge: true,
    }),
    resolve(),
    commonjs(),
    typescript({
      exclude: ["**/*.stories.tsx", "**/*.test.tsx"],
      check: false,
    }),
    scss({ insert: true }),
    json(),
  ],
  external: ["react"],
};

Output: [!] (plugin tailwind) Error: No PostCSS Config found in: D:\workspace\my-app\packages\components

We should either add it to the documentation, or make this not required.
