Update docs with the new api endpoints

[fforbeck]

Hello OpenLaw support, I am working on an application utilizing your API, which appears to have great documentation! However, all of the endpoints I’m trying (https://bakerlaw.openlaw.io/app/login) and (https://app.openlaw.io/app/login) via POST are returning 404 endpoint not found. I’ve tried this using the APIClient as per the documentation and also separately via PostMan. Please let me know what I can do to remedy this issue and properly use the API.
