Describe the bug

When clearing a plot in an area utilizing plot schematics, the schematic will be pasted one block too low.
World-Generation itself works (e.g. //regen works).

The culprit seems to be somewhere here (used by the FAWE Delegate to determine minY for plot schematics):

PlotSquared/Core/src/main/java/com/plotsquared/core/generator/HybridPlotWorld.java

Lines 558 to 560 in a641258

	public int getPlotYStart() {
	return SCHEM_Y + plotY;
	}

When replacing SCHEM_Y + plotY with getMinBuildHeight() (the same reference point the world generator uses, as visible in HybridGen: https://github.com/IntellectualSites/PlotSquared/blob/main/Core/src/main/java/com/plotsquared/core/generator/HybridGen.java#L76) clear works. My only idea for that being is, that one of these two variables is normalized somewhere - possibly against the road height.
I don't just want to PR my fix, as I'm not sure what the reasoning behind the change was (@dordsor21 ?) and if that does not have any unexpected side effects.

To Reproduce

1. Create plot schematic as described in wiki (/plot schematic save, move to appropriate schematic folder)
2. World will be generated accordingly
3. Claim Plot and run /plot clear
4. Schematic will be one block too low

Expected behaviour

The schematic should be pasted from the correct y-level
