Fixes formatting for code block (#3055)

The Rollover page includes a code block that doesn't render as expected,
so I'm removing the `console` option.

-------

Here's how it currently renders:
<img width="874" height="242" alt="image"
src="https://github.com/user-attachments/assets/280f94c8-9464-4f2c-8fe3-f6e8595c0b48"
/>


And here's how I'd expect it to render:
<img width="874" height="242" alt="image"
src="https://github.com/user-attachments/assets/ccdc9e57-3baa-4ce9-a25f-24102ba9a95e"
/>
