Fix incorrect references in markerUnits docs (#3376)

The markerUnits attribute defines the coordinate system for the markerWidth and markerHeight attributes, not markerWidth and markerUnits. This commit changes the docs to match the [SVG 1.1](https://www.w3.org/TR/SVG11/painting.html#MarkerUnitsAttribute) and [SVG 2](https://svgwg.org/svg2-draft/painting.html#MarkerUnitsAttribute) specs.
