Description of the bug

Recent changes to export_model_obj (see #5432) inverted the logic associated to the export into one or multiple objects. From my understanding, the argument export_as_single_objects had the right meaning : "exporting the model into multiple objects" and we should revert the changes that got merged. If the name is confusing then we might want to rename the argument, for example using export_as_multiple_objects to export multiple objects or export_as_single_object to export into one object.

NOTE: The changes make the pyaedt-examples repo failing. Specificly, this example https://github.com/ansys/pyaedt-examples/blob/main/examples/electrothermal/components_csv.py

You are absolutely right, sorry. In my mind, I read it without the final "s" and that changed completely the meaning. If you want, I can revert the changes, or you can do it.

I'll do the changes and modify the name to make it more reader friendly. It is true that the name is a bit miss leading.
