fix: use correct chebyshev calculation in AreaMap

[skerit]

The chebyshevDistance method in the AreaMap class seems to be wrong:

VMP-fabric/src/main/java/com/ishland/vmp/common/maps/AreaMap.java

Line 236 in bee4c78

return Math.min(Math.abs(x0 - x1), Math.abs(z0 - z1));

The current implementation uses Math.min instead of Math.max, even though there are other places in the code where Math.max is used instead:

VMP-fabric/src/main/java/com/ishland/vmp/mixins/playerwatching/MixinThreadedAnvilChunkStorage.java

Line 100 in bee4c78

int chebyshevDistance = Math.max(Math.abs(watchedPos.getSectionX() - chunkPos.x), Math.abs(watchedPos.getSectionZ() - chunkPos.z));

If this was correct I'd love to hear why, if not here's the tiny PR to fix it :)
