100% Wither Skull Drop Rate

Hello! While I've posted a resource pack before, it's my first time getting into behavior packs! Constructive criticism is welcomed of course, but please go easy on me! Either way, this packs changes the drop rate of wither skulls to a 100% chance. From experience, I know it can be super annoying having to spend such a long time farming skulls (since I'm quite unlucky with it), so I changed that!Anyways, enjoy :D
