de487816 - Suppress ty invalid-argument-type false positive in create_kml_geometry

Suppress ty invalid-argument-type false positive in create_kml_geometry ty can't narrow geom/kml_class through the dict-lookup + isinstance dynamic dispatch, so it checks the geometry=geom call against every union member. Suppress with a ty: ignore alongside the existing type: ignore, matching the convention in config.py and kml.py.
