While removing jenkins-bot@ for T220664 i noticed we also still have gerritadmin@wikimedia.org and recipients are just @demon and @hashar
Given recent changes about Gerrit admin roles and that Chad isn't with WMF anymore we should update that.
Separately we would like to move aliases to Google groups handled by OIT in many, but not all, cases (T122144).
