Tutorial tool displaying Python code snippets instead of JavaScript

In the Tutorial Tool, if you have a JavaScript tutorial with spy code snippets, it displays them as Python.
Repro -

• Go to https://makecode.com/tutorial-tool
• Paste in markdown for a JavaScript tutorial, i.e.

Arcade JavaScript Tutorial

@explicitHints true

Step

Instructions here....

sprites.onOverlap(SpriteKind.Player, SpriteKind.Food, function (sprite, otherSprite) {
	info.changeScoreBy(1)
    otherSprite.setPosition(randint(0, 160), randint(0, 120))
    info.startCountdown(10)
})

You'll see the code snippet shown in Python instead -

Start at the Tutorial Tool entry point at https://makecode.com/tutorial-tool and reproduce the issue with the JavaScript markdown and spy snippet shown in the report. Done means JavaScript spy snippets render as JavaScript rather than Python; no source file or test is named in the issue.
