Update next-with-less to 2.0.2

Hello, I'm facing the same issue.

package.json

"dependencies": {
    "antd": "^4.17.2",
    "next": "12.0.5",
    "next-with-less": "^2.0.2",
    "react": "17.0.2",
    "react-dom": "17.0.2"
  },

next.config.js

/** @type {import('next').NextConfig} */
const withLess = require("next-with-less");

module.exports = withLess({
    reactStrictMode: true,
    lessLoaderOptions: {}
})

Despite my previous comment, I can actually reproduce it too. So what was fixed in 2.0.2 resurfaced again with next: 12.0.5

I'm having the same issue with the exact same setup, except I'm using next: 12.0.7
