instrument-projects.adb: remove useless use of container cursor
In a container iteration through a "for Cur in Container.Iterate" loop, the cursor is used only once, to get access to the container element. Switch to the "for Item of Container" loop instead to simplify the code (no need for a declare block anymore: less nesting involved).
