Expand CI templates maintainership
@zj-gitlab and I used to be the https://gitlab.com/gitlab-org/gitlab-ci-yml maintainers.
With gitlab-foss#50289 (closed) we un-vendored CI templates and now everything lives on /lib/gitlab/ci/templates/
.
It was a long time ago when both ZJ and I worked on the CI/CD team, I think it's time to extend the maintainership to those who are actively working on that area.
I'd like to start a trainee program like the one we have for frontend, backend, and database maintainers.
