be used with the Unified Alerting added in v8.0.0[2].

archwiki: update to 1.36.2-1

See merge request !494

Useful for mail.archlinux.org where this setting doesn't matter since we
force the SSH command to passwd and zsh was removed as part of the tools
cleanup effort recently (stops shadow.service from complaining about zsh
missing).

It's not available as a shell anymore after tools were removed from it.
