- Update the best practice is to create an API-only user w/ the admin
role and access only to necessary SCIM API endpoints
- These doc updates require [this
bug](https://github.com/fleetdm/fleet/issues/48062) to be fixed because
the `/scim/*` API endpoints aren't exposed as API endpoints one can pick
when creating an API only user
- Document the `/scim/*` API endpoints
