This PR standardizes the YOLOS model card in the docs. I've followed the template in #36979 as best I can, but I'm not sure if I've done it correctly since the information on this model didn't exactly fit 1-to-1 with the template. I got rid of the table and the images since the other PRs for this did that. Let me know if I need to make any changes.
