fix QuadtreePrimitive updateHeights callback

[calogeromauceri]

Description

This is a trivial fix for changes introduced by commit 53889cb.

After that commit, the callback defined in Scene.updateHeight expects a cartographic position.
This updates ensures that positions retrieved during QuadtreePrivitive.updateHeights iteration are properly converted to cartographic coordinates before being passed to the callback.
This avoids unneeded computation, which is important because updateHeights is time-constraned. Reducing overhead ensures that entity position updates remain performant and consistent.

Thanks for the fix @calogeromauceri. The code change here looks good, and thank you for adding additional tests!

I pushed 53889cb as a fix for a broken Sandcastle (that I missed when reviewing the original PR) during the release. I'll verify everything is still working, and if so, this should be good to merge.

@calogeromauceri Everything looks great. Since a release went out in the interim, would you mind adding an entry to CHANGES.md with a summary of the fix?
