Hello
One golf club with everything in it (trees, grass, buildings, roads, parkings) is just one leisure=golf_course as told on https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dgolf_course
Yours contours are even not match with landuse=grass. You can map grass as landuse=grass and woods as natural=wood. But if you want to add details on golf infrastructure there is an example on wiki page of how to map golf=fairway and golf=green and so on
And there is no need to add area=yes because leisure is always area (and it's not an aera)
