Blitzkrieg 1.11.0

I am going on vacation so I thought I'd publish this a bit prematurely without all the planned features.

Changes

• Added /ratings
  • This command currently only has the leagues subcommand group
  • Displays the top players in a league
  • Also shows the changes in their positions and scores since last region midnight
  • Use /help timezones to know when Blitzkrieg records the leaderboard
• Blitzkrieg now internally generates and keeps a permanent record of all leaderboards updated every UTC+0 midnight
  • This approach will allow us to capture the absolute latest state of the leaderboard before it is wiped for the next season

Fixes

• Removed region "Europe" in /verify example

Technical Changes

• Add scripts were upgraded to TypeScript
• Secrets now only throw errors if they're used when not provided
