Make the buttons in the connection prompts more visually distinct

[Karlo-Emilo]

The options are visually very similar as shown in the pictures beneath.

It would be easier for the user to navigate the prompts if they had different icons and/or colors.

we could use awesome font's USB and bluetooth icons to the initial buttons (connect via usb / bluetooth)

We could use the small microbit logo (https://www.google.com/search?q=microbit+icon&sxsrf=APwXEdeJBnhqB4XR3Bx57vkc23w9P6w6Vg:1685699888169&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjtyKC4qaT_AhXQSPEDHRInD1UQ_AUoAXoECAEQAw&biw=1680&bih=804&dpr=2#imgrc=Eitj6FuubHJHHM) and another where two of them are stacked on top of eachother to indicate if they would like to use the same or use two micro:bits.
