AntiShadowPatch

• Fixed a bug where picking up an overstacked item would split its contents into multiple slots.
• Renamed BringBackOverstackedItemMovement to BringBackOverstackedItemMovement_1_20.

• Added BringBackCurseBookOverstacking that reverts MC-157133
• Added BringBackOverstackedItemMovement that allows overstacked items to be properly moved once again.
  The behavior should match that of the old one, however it is still experimental, so there might be bugs.

• Updated to 1.21.5
  In this version, Mojang made some changes to how the game handles block entity removal. Features of this mod should work correctly, however there might be some bugs. Also, as part of those changes, now every block that is able to have a block entity can preserve a block entity of a different type, even if you replace that block multiple times over.
