OpenBao maintainers group
## Problem to solve
- We need an easy way to update the maintainers of the GitLab engineering projects related to OpenBao.
- It should be easy to ping these maintainers.
Right now individual team members are listed as code owners.
See https://gitlab.com/gitlab-org/cloud-native/charts/openbao/-/merge_requests/40#note_2812376355
## Proposal
Have a dedicated GitLab group, and use it as the SSoT for project maintainers.
## Implementation plan
- [x] Can we use the `gitlab-com/openbao`? No, not under `gitlab-org/maintainers`.
- [x] Delete [gitlab-com/openbao](https://gitlab.com/groups/gitlab-com/openbao) group.
- [x] Create a new GitLab group: `gitlab-org/maintainers/openbao`
- [x] Add users to group as owners.
- [x] Change Code Owners to group in https://gitlab.com/gitlab-org/govern/secrets-management/openbao-internal
- [x] Change Code Owners to group in https://gitlab.com/gitlab-org/cloud-native/charts/openbao/
- [x] Change Code Owners to group in https://gitlab.com/gitlab-org/govern/secrets-management/gitlab-secrets-manager-container
- [x] Invite group as maintainer for https://gitlab.com/gitlab-org/cloud-native/charts/openbao/
- [x] Invite group as maintainer for https://gitlab.com/gitlab-org/govern/secrets-management/
- [ ] Update maintainers in `team_members/data` files. That's the source of the [Engineering Projects](https://handbook.gitlab.com/handbook/engineering/projects/) page and the [Roulette config](https://gitlab-org.gitlab.io/gitlab-roulette/roulette.json).
- [x] Use group in https://gitlab.com/gitlab-org/frontend/renovate-gitlab-bot/-/merge_requests/1308#note_2887853422
- [x] Update https://gitlab.com/gitlab-com/gl-infra/platform/runway/provisioner/-/blob/265c3943cb5744636694fe99d25c01ddd54d2990/config/runtimes/cloud-run/workloads.yml#L282-288
