Refactor ImplementationIssue to take a single issue argument
While looking into our options for gitlab-com/gl-infra/delivery#1162 (closed), I realized we'll probably end up shortening the output by showing the reference (e.g., gitlab-com/gl-infra/delivery#991
), rather than the full URL. At which point I realized we'd need another attribute from the issue API response, so I figured let's pay this technical debt now.
