Issues Analytics: Table enhancements
### Problem to solve
- Issues analytics only shows opened issues - this information isn't too valuable by itself.
- Related to [Q3 Dogfooding OKR](https://gitlab.com/gitlab-com/www-gitlab-com/-/issues/8303)
### Intended users
* [Parker (Product Manager)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#parker-product-manager)
* [Delaney (Development Team Lead)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#delaney-development-team-lead)
### Proposal

- Add at project-level
- ~~Add closed issues content to data table~~ Already done here: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/38906
- Convert the issues table to using GraphQL to fetch issues: https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/assets/javascripts/issues_analytics/components/issues_analytics_table.vue#L115-126
- Add iteration column to data table
