### Background Like we do in the [Projects API](https://docs.gitlab.com/ee/api/projects.html#edit-project), we need to allow moving the group wiki shard from one node to another. For this, we need to add a new `repository_storage` param (available only for admins) to either the [Groups API](https://docs.gitlab.com/ee/api/groups.html#update-group), or a new Wiki API endpoint. For project wikis, this is currently handled in `Projects::UpdateRepositoryStorageService`. ### Links - Epic for doing the same with snippets: https://gitlab.com/groups/gitlab-org/-/epics/3393
