## What
Based on some customer feedback that our setup guides were a bit
difficult to follow and they just wanted a one page step-by-step.
- Adds a straight shooting one-page guide for folks embedding us into an
existing application
- Moves existing getting started guides that showcased demo applications
into a "Tutorials" area
This does depend on https://github.com/airbytehq/sonar/pull/1049 being
merged, which moves the Applications Token endpoint to the public Sonar
API (another request from that customer!)
