Improve how docs work with thegraph.market relative to getting JWT for the token api

The UX using the Token API from within the docs is not the greatest because of the authentication requirements. We have a better way to do that now. Example is on https://token-api.pinax.network/ - Click Login (top right) - That directs you to https://thegraph.market/auth/tokenapi-env in a new window - You can then copy/paste your JWT back to the application and save it as a cookie. Hopefully this is not a huge effort to replicate this kind of flow in the docs.
