Added "Copy To" in the scenes right click context menu

I have added a "Copy To" menu item to the scenes right click context menu below "Copy".

When clicked on it will open a "Open" Dialog then the user can select the scene collection file the user wants to copy the scene to then a dialog will open telling the user the copy was successful or the scene already exists in the selected scene collection.

I believe this is useful for users that want to copy scenes or move scenes to a different scene collection.
