[Wiki] Broken platform images on build page

[JoshEngebretson]

@christoffersch Great job converting all the image links to use local versions of the image files 👍

It looks like the platform pngs have issues on the editor build page, they won't display in windows either when cloned from the repo

Can we switch up to use the same logos as on the downloads here? http://atomicgameengine.com/#download-the-atomic-editor

Can use the same sizing as currently on the wiki page, though definitely want the Windows 10 logo instead :) Thanks!

I'm on it! :) Yes, we'll use the same icons.

Should be good now 👍
