Add img-left and img-right to grid-item-card #211

Context

Hi!

I am desinging a homepage for a doc site, using icons and text. Having all the icons above the text gets a bit boring and I wanted to switch it up with having a section where icons are on the left side of the clickable card.

Proposal

I was thinking that it would be useful to have a way to add an image on either side of the card. Just like what is done with card-images but with img-left and img-right additionatlly.
