Description
Doc refers to SAPI endpoints on the Leap Dashboard; these have been removed.

To Reproduce
Look https://docs.ocean.dwavesys.com/en/stable/overview/sapi.html
Note paragraph stating:
"You can find all the above information when you log in to your D-Wave account. For Leap users, select the Dashboard tab; for on-premises (Qubist) users, select the Solver API tab and the API Tokens menu item under your user name."
