NEXTAUTH_URL_INTERNAL exists only in the documentation

Describe the bug
Hi!

I started to write the Helm Chart to deploy TypeBot on Kubernetes.

I set the env variables, including NEXTAUTH_URL (https://chatbot.example.com) and NEXTAUTH_URL_INTERNAL (http://typebot-builder.typebot.svc.cluster.local:3000), but the NEXTAUTH_URL_INTERNAL env variable is never used.

I looked into the code and found that NEXTAUTH_URL_INTERNAL is not mentioned except in the documentation, where it is everywhere.

To Reproduce
Steps to reproduce the behaviour:

1. Search in the code the NEXTAUTH_URL_INTERNAL in your IDE (VScode, for example)
2. Only the related documentation will mention this ENV variable, not any code-related.

Expected behavior
Call internally the builder instead of its public URL

Thanks for the heads up!
