import webpack not webpack5

[imranbarbhuiya]

next/dist/compiled/webpack/webpack exports webpack5 as webpack so we need to import webpack and not webpack5 inside https://github.com/vercel/next.js/blob/canary/packages/next/server/config-shared.ts#L2

next/dist/compiled/webpack/webpack

exports.init = function () {
  if (process.env.NEXT_PRIVATE_LOCAL_WEBPACK5) {
    Object.assign(exports, {
      webpack: require('webpack5'),
    })
  } 
}

https://github.com/vercel/next.js/blob/canary/packages/next/server/config-shared.ts#L2

import type { webpack5 } from 'next/dist/compiled/webpack/webpack'
