Handle when aud OIDC claim is an Array (#4584)

* Handle when `aud` OIDC claim is an Array

The `aud` claim of OIDC id_tokens [can be an array](ce6d694639/src/Claims.ts (L92)) but the existing logic
incorrectly assumes `aud` is always a string.

This PR adds the necessary check.

* Clarify `aud` OIDC claim check

* Fix for prettier
