"File is not a constructor" in Node 16 and below

I have the following index.js

```js
const { File } = require('buffer');
console.log(new File(['Hello World'], 'hello.txt'))
```

`node index` succeeds on Node `v20.0.0` and `v18.16.0`.

`node index` fails with the following error on Node `v16.20.0` and `v14.21.3`

```bash
console.log(new File(['Hello World'], 'hello.txt'))
^
