Dragon Slayer skin uses the slim model instead of the classic model

Skin is made for Steve skin model but it has Alex skin model so there are blue lines on the hand.

Steps to Reproduce:

1. Get the Lego Minecraft End Battle 21151 set.
2. Go to website in instructions and enter code from the brick to get the skin. You will need to be signed in with Microsoft.
3. Go to Minecraft and you should have the Skinpack in about 1-10 minutes.
