Expose archiveGroup in Groups.userPermissions GraphQL API

Needed for Add archiving to quick actions in list views (#554023 - closed)

We need to expose the archiveGroup userPermissions on the Groups GraphQL API. This should represent the user's ability to archive/unarchive the group.

Implementation Guide

  1. Explose archive_group in https://gitlab.com/gitlab-org/gitlab/blob/fbcdc8185b4e3819075c0bcae86ee6193ef2252b/app/graphql/types/permission_types/group.rb
  2. Run bundle exec rake gitlab:graphql:compile_docs to regenerate the docs.
