Fix image links in Modrinth description

Modrinth proxies images hosted on non-trusted domains through wsrv.nl,
for understandable reasons. However, wsrv.nl blocks tweaked.cc - I'm not
sure why. Instead we reference the image on GH directly, which works!

Also:
 - Fix the modrinthSyncBody task pointing to a missing file.
 - Update the licenses of a few files, post getting permission from
   people. <3 all.

 While computers are incredibly powerful, they're rather limited by their inability to move about. *Turtles* are the
 solution here. They can move about the world, placing and breaking blocks, swinging a sword to protect you from zombies,
 or whatever else you program them to!
