Delete non-existing unboxed DSUB HD connectors
There are no unboxed DSUB HD connectors with EdgePinOffset9.40mm
See merge request kicad-footprint-generator!1088 (merged) and kicad-packages3D!997.
I started working on other fixes to be matched with footprint updates, but others might require changing source code, so I decided to just push the trivial one.
