Next.js forcibly setting `module: 'esnext'` in `tsconfig.json` is necessary to prevent TypeScript from erroring on the following code:
```tsx
import dynamic from 'next/dynamic';
const A = dynamic(() => import('../A'));
```
```
ERROR in /Users/joe/Desktop/scratch/test-cjs/pages/index.tsx(5,25):
5:25 Dynamic imports are only supported when the '--module' flag is set to 'es2020', 'esnext', 'commonjs', 'amd', 'system', or 'umd'.
> 5 | const A = dynamic(() => import("../test"));
```
However, users may want to use one of the many other targets for better interoperability with projects that co-exist with their Next.js project (like `commonjs`).
When cross referenced with:
```
Option '--resolveJsonModule' can only be specified when module code generation is 'commonjs', 'amd', 'es2015' or 'esNext'.ts
```
That means we can permit any of these values:
```json5
parsedValues: [
ts.ModuleKind.ES2020,
ts.ModuleKind.ESNext,
ts.ModuleKind.CommonJS,
ts.ModuleKind.AMD,
],
```
This PR updates Next.js to allow those!
