This worker was first added in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/1144 in %"8.17" but
all usages were removed in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/13437 in %"12.0" .
Given that the usages of this worker have been removed for at least 1
major release now we should be safe to remove this worker itself. In
fact we could have removed it already in %"13.0" .
