Consider adding a static site for HackPacks

Make a site to show off the hackpacks we've built! 

Could have: 
- Descriptions
- Number of star
- Ability to filter by language/technology/level (ie. the iOS HackPack would be discoverable through searching for Swift, iOS, Mobile, Beginner)
- Request for additional hackpacks?

I think a card style similar to what was used for the sponsors API section would be logical.
