DIBs: Development-Impeding Bugs

1. Sculks get triggered by area_effect_clouds getting /killed. https://bugs.mojang.com/browse/MC-220397
	- Malefit: This means sculks are useless around piston trackers.
	- If fixed: No action required.
2. The volume defined by target selector arguments "dx", "dy" and "dz" is always larger than specified by 1 in all dimensions. https://bugs.mojang.com/browse/MC-123441
	- Workaround: Used dx=0,dy=0,dz=0 instead of dx=1,dy=1,dz=1.
	- If fixed: Change all instance of "dx=0,dy=0,dz=0" to "dx=1,dy=1,dz=1".
3. Copper slabs and stairs are not included in the #minecraft:slabs and #minecraft:stairs tags https://bugs.mojang.com/browse/MC-208075
	- Workaround: Added them using appending tags.
	- If fixed: Delete the appending tags.
