Cube Playground cannot generate YAML data model

**Describe the bug**
I am running the `cubejs/cube:latest` docker image against a database.
When I check the **Data Model** section, I can list the Tables but I can only generate Javascript models.
**Yaml generation is disabled** because I seem to be on an Tables
3. Try to generate a YAML data model, it will be disabled

**Expected behavior**
You can generate YAML data models in a local Cube Playground

**Minimally reproducible Cube Schema**
N/A

**Version:**
v1.1.2

**Additional context**
Not sure if related, but the context also sends `telemetry: false` and yet I see calls going to segment.io. Maybe the context is just not parsed correctly at all by the React code?
