Fix: patroni alerts expressions, include all database cluster nodes, except backup, archive and delayed nodes

Related to Bug: #142 (comment 1670346621)

Currently we have the following on https://gitlab.com/gitlab-com/runbooks/-/blob/master/libsonnet/alerts/patroni-cause-alerts.libsonnet#L9

local selector = { type: 'patroni' };

This generated the alert files, like https://gitlab.com/gitlab-com/runbooks/-/blob/master/thanos-rules/autogenerated-patroni-cause-alerts-gprd.yml

Whether we want to have these alerts for other patroni services too, i.e. patroni-registry, patroni-embedding, patroni-ci.

A better outcome that removes backup, archive and delayed nodes would be through tier="db", env="gprd", type!~".*archive", type!~".*delayed"
