### What?

### Why?

### How?

Closes NEXT-
Fixes #

-->


### What?

Prevent confusing error messages when changing to `"type": "module"` in
`package.json`

```
./node_modules/next/dist/build/webpack/loaders/css-loader/src/index.js??ruleSet[1].rules[2].oneOf[8].use[1]!./node_modules/next/dist/build/webpack/loaders/postcss-loader/src/index.js??ruleSet[1].rules[2].oneOf[8].use[2]!./src/styles/index.css
Error [ERR_REQUIRE_ESM]: require() of ES Module /path/to/my/repo/components/postcss.config.js from /path/to/my/repo/components/node_modules/next/dist/lib/find-config.js not supported.
Instead change the require of postcss.config.js in /path/to/my/repo/components/node_modules/next/dist/lib/find-config.js to a dynamic import() which is available in all CommonJS modules.
```

### Why?

Even though PostCSS itself [supports ESM and TypeScript configuration
files](https://github.com/postcss/postcss-load-config/issues/230),
Next.js itself does not (because of `next/lib/find-config`):

- https://github.com/vercel/next.js/issues/34448

### How?

By switching to `.cjs`, the config will stay recognized as CommonJS even
after switching to `"type": "module"` in `package.json`
