kube-prometheus-stack (Helm chart): 87.7.0 → 87.9.0

Verdict: Safe to merge

Chart-only minor bump. The pinned upstream components are unchanged across 87.7.0, 87.7.1, 87.8.0, and 87.9.0:

• prometheus-operator appVersion: v0.92.1
• kube-state-metrics: 7.5.1
• prometheus-node-exporter: 4.55.0
• prometheus-windows-exporter: 0.12.*
• grafana: 12.7.2

The only changes between 87.7.0 and 87.9.0 are additive — three PRs that expose additional spec fields to the chart (ThanosRuler, Alertmanager, Prometheus). No breaking changes, deprecations, or behavior changes.

Repo impact: kubernetes/apps/observability/kube-prometheus-stack/app/helmrelease.yaml and the helmfile CRD pin were both updated in the diff. The existing values use alertmanagerSpec.alertmanagerConfiguration, prometheusSpec (with an explicit Prometheus version override and a custom PromPP image), and selector flags (*SelectorNilUsesHelmValues: false). None of these are affected by the chart bump — the additive spec fields are opt-in and we do not need to use them.
