[otel_collector_internal_telemetry] Clarify that prometheus format is not supported

[gregkalapos]

Adding docs clarifying which metric format the dashboards expect.

[github-actions]

TL;DR

The Buildkite failure is caused by invalid YAML in packages/otel_collector_internal_telemetry/changelog.yml at line 4. Quote (or block-style) the changelog description value because it contains a colon (Doc update:), which currently breaks YAML parsing.

Remediation

• Update packages/otel_collector_internal_telemetry/changelog.yml:4 to quote the description, for example:

  - description: "Doc update: Clarify expected metrics format and explicitly calling out that Prometheus format is not supported."

• Re-run package lint for this integration (the failing Buildkite step is test_one_package.sh packages/otel_collector_internal_telemetry ...) to confirm parsing succeeds.

Investigation details

Root Cause

changelog.yml in the PR head contains an unquoted scalar with : inside the value:

• File: packages/otel_collector_internal_telemetry/changelog.yml:4
• Current value in PR head:

  - description: Doc update: Clarify expected metrics format and explicitly calling out that Prometheus format is not supported.

YAML treats : as a mapping delimiter unless safely quoted/escaped in plain scalars, so lint fails while unmarshalling.

Evidence

• Build: https://buildkite.com/elastic/integrations/builds/43658
• Job/step: Check integrations otel_collector_internal_telemetry (.buildkite/scripts/test_one_package.sh packages/otel_collector_internal_telemetry origin/main 5c8d05a4de84c36a62a88e7645017156ce7d88e1)
• Key log excerpt:

  Error: checking package failed: linting package failed: found 3 validation errors:
  1. .../packages/otel_collector_internal_telemetry/changelog.yml" is invalid:
     unmarshalling YAML file failed: yaml: line 4: mapping values are not allowed in this context
  

Verification

• Not run locally in this workflow; diagnosis is based on Buildkite logs and PR content at commit 5c8d05a4de84c36a62a88e7645017156ce7d88e1.

Follow-up

• After fixing the quoted string, re-trigger CI for this PR.
