Add hackathon results to site

[tobeycodes]

We should add the hackathon results to the site.

• Add a static image from the slides
• Add a link to the colloseum blog post
• Add a video embed of the section where we are announced as winners

I think it would also be nice to add the hackathon winner to the hero of the homepage. Similar to what https://nomadz.xyz/ have done
