Alphabetically sort MTGO Cubes so they are easier to find

Implements #6200.

I have one commit as moves and one commit as edits for easier reviewing. It's too bad that it didn't show them as moves for all the .draft files in github, but that's out of my control.

Is this going to cause issues for people who are in between gauntlets, or have their preferences pointed to the old names?

@tehdiplomat, I'm unfamiliar with Gauntlet, but as far as I can tell from playing with the UI it doesn't seem related to draft or cube so I think those are totally separate and safe if in progress.

As far as drafted decks from a cube go, the decks seem unrelated to the cube they were drafted from. And there's no in progress saving of a draft, so nothing to worry about from that front.

@tehdiplomat I triple checked all changes after fixing the 1 typo I found.
