Subject: [PATCH] chore(telemetry): update Prometheus to v3.13.2

Moves off the v2.53 LTS line, which this branch pinned, onto the current
v3 release, and corrects the accompanying comment that named the old line.

Verified against the new image rather than assumed, since this crosses a
major version:
  - prometheus.yml passes `promtool check config` under v3.13.2
  - all 391 unique dashboard PromQL queries parse under the v3 parser
  - all 13 alert-rule expressions parse under the v3 parser

The config uses none of the surfaces v3 changed: no remote_write, no
holt_winters, no offset modifiers.
