List the approval rules in the reviewers drawer
In the reviewers drawer component we need to list all the current approval rules for the merge request. See #441689[reviewer-assignment.png] for the design.
There is a component in the approvals widget that already does this (https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/assets/javascripts/vue_merge_request_widget/components/approvals/approvals_list.vue). I don't think we can use this component as the markup will be very different. But maybe we can re-use the GraphQL query that gets the data?
