Look at getting the card list updates out of main

[haganbmj]

Originally this was set up with a few motivations.

• Only pull "all cards" from scryfall once a week.
• Cache the resolution so that it's not spending extra time pulling+updating that.
• Avoid having to do gitignore trickery for local build support.

But now it's just extra commits to main and the commit frequency is low enough that I could probably just pull it on deploy.
