Make QueryCarousels Edition Aware

[benbdeitch]

Closes #7252

As of this moment, carousels link to and display works, rather than specific editions. This prevents users from specifically locating given editions of works on carousels, which is not ideal. This PR alters the functionality of carousels to link to and show covers of editions rather than works.

Technical

This issue originally called for restricting the editions that show to ones matching the user's language. In the name of getting this feature out sooner, that has been left out on Drini's advice, to be achieved in a later PR.

Testing

Create a new page on your local version, and create a Carousel macro. {{QueryCarousel("*")}} should be a functional command.

So, this mostly works so far. I'm still ironing out a few kinks. I've stopped it from breaking the current macro, but haven't yet figured out why the addition of 'lang' causes problems. Also, it doesn't yet show editions, which is a problem.

Alright, everything should be good to go here. The commit history is slightly messy, but nothing that should cause a problem. It's been tested on my end, and works fine.
