Console button shouldn't appear in non-JS challenges

## Description

I'm too lazy for a screenshot, but there’s a screen recording in #1662. The console button shows up on the action bar even though the challenge doesn't involve JS.

App version: 6.0.1

Start by reproducing the issue from the screen recording in #1662 with a non-JS challenge, then locate the action bar logic that controls the console button. Done means the console button is absent for non-JS challenges while remaining available for challenges that involve JavaScript.
