Hierarchy widget - add an endpoint for listing work items
When adding child work items in the hierarchy widget, UI will need to fetch a list of existing work items for the autocompletion (probably using filtering by work item type). We should add a graphql API endpoint which allows this listing.
Currently we have endpoint for getting only single work item (by its ID).
