release-25.4: roachprod: bump local Prometheus version to 2.53.5

[blathers-crl]

Backport 1/1 commits from #170676 on behalf of @Dev-Kyle.

---

The local Prometheus version (2.27.1) is over 4 years old and has been observed crashing in CI (e.g. #169503 on s390x). This commit bumps it to 2.53.5, the latest patch in the 2.53 LTS series.

We choose to stay on 2.x instead of upgrading to 3.x to avoid any breaking changes. The 2.x bump is sufficient to address the stability issue mentioned above and will act as an drop-in replacement before we move away from Prometheus entirely (VictoriaMetrics).

The 2.53.5 tarballs have been uploaded to
gs://cockroach-test-artifacts/prometheus/ for amd64, arm64, and s390x. No testdata regeneration was required because PrometheusVersion is not embedded in any cloud-provider startup script.

• Other approved changes. These changes must be gated behind a disabled-by-default feature flag unless there is a strong justification not to. Reference the approved ENGREQ ticket in the PR body (e.g., "Fixes ENGREQ-123").

Add a brief release justification to the PR description explaining your selection.

✅ PR #170745 is compliant with backport policy

Confidence: high
Backward compatible: true
Explanation: The pull request is compliant with the backport policy for CockroachDB as it involves changes to non-production code, specifically to support testing environments. The PR title and body indicate that the update is for roachprod, which is used primarily in testing and not in production environments. It upgrades the Prometheus version used in testing to address observed stability issues without changing any production behavior. Furthermore, the release justification explicitly mentions 'Test only changes', clearly aligning with the exception for test-only changes in the backport policy. Additionally, the Labels field in the PR details includes 'T-testeng', further supporting that this change is relevant to testing infrastructure.

✅ ENGREQ Check Skipped: Test-only backport.
