Website: Add Trailer and More Prominent Link to GitHub

[Erin-Cecele]

Before proceeding, check to make sure there isn’t an existing issue for your suggestion or a similar one.

• [X] I have searched the existing issues and determined this is new suggestion.

Idea being proposed

• [ ] Link to trailer as "watch video" front and center on the homepage. Like Manifold. https://manifoldapp.org/
• [ ] Add poster image to video. I propose one of the two options I've included in the "Supporting information" section, but I'm open to suggestions
• [ ] Make link to GitHub repo more prominent. @hbalenda suggested making the link a top-level navigation item.

What contribution category does your proposal fall under?
