Missing polyfill for middleware: URLPattern

[mbaquerizo]

next.js implements URLPattern for edge runtime middleware. After upgrading sst, and by extension open-next@3, my middleware broke because URLPattern is not a constructor.

If I need to provide a reproduction, let me know. Tested and working with https://www.npmjs.com/package/urlpattern-polyfill for now as a workaround.
