Docs: Add screenshots of each component in docs

[jamonholmgren]

It would be really nice to have screenshots of each component, maybe right below the code snippet. Should be relatively simple to add. I recommend hosting the images in here OR just uploading them to this issue and capturing the URL.

@jamonholmgren / @yulolimum Do you have any suggestions on good screenshot taking for such a thing? I'd normally just ctrl+cmd+shift+4 but they won't be framed nice or even sized I guess.

Or we could just screenshot the showroom screen part of each one I guess
