these images never appear in the extrusion depth menu, drop them

Extrusion depth is just a simple menu

where 6 of the strings are already just string resources, doing a full docking
window res to .ui conversion for the two remaining strings seems overkill

put back the images, they were visible in some configurations

I forgot that images in menus are automatically shown/hidden
depending on platform. So put these back again
