Updated the docs so chatbots can use the Conduit API

Summary: Previously, the chatbot docs instructed users to get certificates for the conduit API and put the cert in a `conduit.cert` config key. In order to get the chatbot to work, I needed to instead get an API key and put it in the `conduit.token` config entry.

Test Plan: Doc fix. Tried the new documented way and it worked.
