Improve use of "image" jargon

[JohnVeness]

Section https://www.raspberrypi.com/documentation/computers/getting-started.html#installing-the-operating-system explains that you'll need "a computer you can use to image the storage device into a boot device".

For those new to Raspberry Pi, the use of "image" as a verb may be unclear. Even for someone who knows about writing images to SD cards, "image the storage device into a boot device" is a bit clunky.

To be honest, probably you could just have "a computer" as the first bullet point!

Also, I think it might be worth a sentence explaining what we mean by "image" (as a noun) too, given how people might initially associate that word with pictures/photos.
