Hi there,

The node example provided (https://github.com/mozilla/pdf.js/tree/master/examples/node) fails on node.js >= 16.7. I believe that's due to the fact that the runtime is checked via `URL.createObjectURL` in `legacy/build/pdf.js` (repo: https://github.com/mozilla/pdfjs-dist/blob/master/legacy/build/pdf.js#L2459) and the fact that it has been recently introduced in node 16.7 (see: https://nodejs.org/api/url.html#urlcreateobjecturlblob)

Configuration:
- Node.js 16.7 or 16.8
- PDF.js version: latest

Steps to reproduce the problem:
1. Run pdf.js node example with node 16.7 or later

Error:
`stack:'ReferenceError: Blob is not defined\n    at createObjectURL`

Thanks!
