Keycloak: calls to endpoint userinfo should use serverUrlInternal #413
Description
The OAuth module for Keycloak has a configuration parameter serverUrlInternal that is useful when the internal Keycloak URL (e.g., from the Nuxt server) is different from the public URL.
The problem: When calling /protocol/openid-connect/userinfo, the module uses serverUrl instead of serverUrlInternal even though it is also an internal request.
The solution: a one-liner that replaces serverUrl with serverUrlInternal.
