Prettier dates by default

Ideally these would use a site config, but let's avoid showing this out of the box:

BOOOOOOOOO.

I'm not sure if it'd be best to use GraphQL here or a third-party library.

A third-party will give us a lot of control and allow for nice, dynamic display of things like "X minutes ago" that actually update.

moment is the obvious choice but it's big and a bit unwieldy to work with. https://github.com/iamkun/dayjs looks nice, and there's also https://moment.github.io/luxon/ and something else I'm forgetting.

Cool, I'm down with using something different. I don't really have any special preference either way so I'm good with whatever you'd like to use! Of the three, maybe dayjs?

It seems the smallest and the nicest, but still has i18n support for when we want it. I’m probably game.
