Grafana: 13.1.8 → 13.2.0

Upgrade impact: Minor upgrade. Minor releases are usually backwards-compatible, but can add or change behaviour — test in staging before production.

Fixed by upgrading to 13.2.0 iVulnerabilities that affect 13.1.8 but no longer affect 13.2.0 — the security gain from this upgrade, by exploited status then exploitation probability.

Exploited first, then by exploitation probability (EPSS).
