[MCPE-147373] Transition from stone to deepslate starts at the wrong layer

The transition from stone to deepslate is supposed to happen between layers Y= 8 and Y= 0, just like Java Edition. It allows for a proper smooth transition when old bedrock gets converted to deepslate.

However, the transition currently happens between layers Y= 0 and Y= -8, which is both a disparity and causes a clash in world conversion.

Looking further, apparently, this is more of a parity issue since on Java 21w44a, they changed the starting full deepslate layer from y=-8 to y=0. Essentially, shifting the transition layer by 8 blocks upwards.

This issue also makes deepslate coal/copper/emerald (the silk-touched unsmelted form) much harder to obtain in Bedrock edition. Hopefully this is fixed soon!

This issue will also create strange clashes with varying deepslate layers on preexisting worlds. Wonder why it didn't make it into full release.
