Parity change to the upcoming game drop.

Java beds have always had a 3d item model compared to bedrock's niche looking ones especially with the addition of straw beds which look so good in bedrock and fit perfectly with the game vibe, I find this a great opportunity to make this parity change because of the addition of the "cushion" which got a 2d item model texture on both java and bedrock, as it will make things more consistant .
