Send `/-/work_items` path on list view

Work items are viewed on the /-/work_items route such as https://gitlab.com/gitlab-org/plan-stage/test-project/-/work_items/104945157

However, the GraphQL API gives work item paths/urls as /-/issues routes instead of /-/work_items routes. They should be /-/work_items routes.

// https://gitlab.com/-/graphql-explorer
{
  project(fullPath: "gitlab-org/plan-stage/test-project") {
    issue(iid: "73") {
      id
      title
      webPath
      webUrl
    }
  }
}

// response
