fix: update broken authenticated tool helper (#599)

* fix: update broken authenticated tool helper

* fix: Update invalid auth config argument reference in helpers

* fix: Incorrect code example for `get_auth_config`

`auth_request_function_call`'s args values are dictionaries, meaning it will never be an instance of AuthConfig by default
