Write fetch handler so that npm run start works

[juanmirocks]

Write a default fetch handler like the JS example: https://github.com/cloudflare/workers-sdk/edit/main/packages/create-cloudflare/templates/scheduled/js/src/index.js

Without it, npm run start / dev will point to a browser location that does not exist.
