Better gems page

[timriley]

The gems page is pretty barebones right now. If we pull the "highlighted gems" off the home page in #133, we'll need a better place to showcase them. I'm thinking we could do the following to improve the gems page:

• Add a "featured gems" area for the popular/important ones
• Do something to make the full listing look a bit nicer. Fatten things up, offer links to both docs and source code, maybe even relevant guides with dry-rb.org (once we add them).

Perhaps something similar to (or just the top part of) the boxes on Ruby Toolbox?

dry-rb.org is statically generated, so displaying real-time or near real-time data might be difficult.

Using a client-side script to fetch that data may be reasonable, but we need to research tools for that

Maybe a statically-generated nicer layout, like a CSS+HTML grid of cards? Spruce up the appearance a bit, and make highlighted Gems distinctive by colour (and appropriate ARIA attributes)?

I like the idea of cards, they could include gh stars/watchers/used by badges too.
