Third Party Auth JWT not compatible with Edge Function

[PBJT2]

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

Following the guide at Supabase Auth0 Integration Docs.
I was not able to use the JWT issued by Auth0 to invoke my edge function.
I was able to use the JWT issued by Auth0 to query the database.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Follow the guide at Supabase Auth0 Integration Docs for setup.
2. Attempt to invoke Edge Function with a JWT issued by Auth0

Expected behavior

Auth0 JWT should be a valid JWT to invoke the edge function with.

System information

• OS: Windows 11
• Version of supabase-js: 2.49.4
• Version of Node.js: 22

This seems to be an issue with Edge Functions and its JWT token verification.
It does not appear to be directly related to edge-runtime, but FYI @laktek.

This relates to https://github.com/orgs/supabase/discussions/34988 - would love to get some supabase team commentary on this as the docs are a bit vague on Clerk <-> Supabase inteagration regarding the jwt flag!
