Desktops and All-in-one devices show a laptop icon when looking at certified device pages

[pieqq]

Summary

When looking at a Desktop or All-in-One certified device, the device icon is a laptop, which is a bit misleading.

This is because both Desktops and Laptops categories are set to use the Laptop SVG icon.

Steps to reproduce the behavior

1. Go to https://ubuntu.com/certified/202401-33373
2. This is an All-in-One system, but the icon on the right of the page shows a laptop (Not OK)
3. Go to https://ubuntu.com/certified/202207-30449
4. This is a Desktop system, but the icon on the right of the page shows a laptop (Not OK)

Expected behavior

The icon used should match the device on the page. If it is a desktop, it should look like a desktop (a tower with a screen, for instance). If it's an All-in-One, it should also look like one.
