LiChess Tools off for a few hours

Lichess just made an update that breaks LiChess Tools and I am out of town. I will fix it in 6-7 hours when I get back. Sorry for the inconvenience!

The Lichess bug was fixed, so the extension works again, but I will make sure this doesn't happen again ( in the same way :D ).

False false alarm. The code actually needed changing while Lichess fix their own bug. New version 2.3.69 will be available soon with the fix.
