Ore distribution doesn't match with Java 21w40a

The latest Java snapshot 21w40a changes the ore distribution once again, like the following:

• Copper Ore now generates between Y=-16 to Y=112, generating the most at Y=48, and increased the number of blobs.
• Added more unexposed Diamonds.
• Decreased minimum generation height of Emerald Ore from Y=32 to Y=-16, and increased the number of blobs.
• Extra gold generates below Y=-48.
• Decreased minimum generation height of the upper range of Iron Ore from Y=112 to Y=80, and increased the number of blobs.

Bedrock Edition hasn't got these changes so far, which breaks parity.
