Describe the bug
I see this warning when integrating Inngest into a new Next.js project:

 ⚠ ./node_modules/cross-fetch/node_modules/node-fetch/lib/index.js
Module not found: Can't resolve 'encoding' in '/Users/ian/Code/promptmetrix/node_modules/cross-fetch/node_modules/node-fetch/lib'

Also seeing this same issue with Next.js v13.5.6 app router.

Import trace for requested module:
./node_modules/node-fetch/lib/index.js
./node_modules/cross-fetch/dist/node-ponyfill.js
./node_modules/inngest/helpers/env.js
./node_modules/inngest/components/InngestCommHandler.js
./node_modules/inngest/next.js
./src/app/api/inngest/route.ts

For now, I've installed encoding manually with yarn add -D encoding to get around the issue.
