Description

Using Next 14 with edge runtime (export const runtime = 'edge') nextjs-auth0 lib throws an error about not being able to resolve crypto module - which makes sense, only subtle crypto is available in edge.

Suggested solution 1 - implement crypto "stuff" using subtle crypto as that is reliably available in Edge, Node and browser
Suggested solution 2 - do not load DPoP utils if they are not being used (for example we use edge runtime, but not DPoP)

Reproduction

1. git clone https://github.com/energyaspects/nextjs-auth0-crypto-module-not-found
2. npm install
3. npm run dev
4. GET /api/edge
5. Error is thrown

 ⨯ ./node_modules/@auth0/nextjs-auth0/dist/utils/dpopUtils.js:1:1
Module not found: Can't resolve 'crypto'

Additional context

Its likely happening due usage to webpack - same happens with Next 15 using webpack.
