Issue:
None

Link to docs preview:

What

  • New page observability/opentelemetry: export flow, DNS, and audit logs and component metrics over OTLP through the operator-managed OpenTelemetry Collector (LogCollector spec.openTelemetry).
  • "Archive logs" moves from observability/elastic/ to observability/, next to the new page, and gets an OpenTelemetry tab. OpenTelemetry is added to the destination lists in the logs overview and the install options table.
  • Removes "only Splunk Enterprise is supported": the operator posts to any Splunk HTTP Event Collector endpoint, which Splunk Cloud Platform also provides.

Why
The openTelemetry API is in the operator reference with no user guide. Export destinations also sat under the Elasticsearch section although they don't depend on it.

Behavior change
/calico-enterprise/3.24/observability/elastic/archive-storage moves to /calico-enterprise/3.24/observability/archive-storage at EP3. A commented redirect is in static/_redirects; uncomment it when EP3 publishes.

Test plan

  • Built next locally on the first commit: no broken links. Later builds were killed by the OOM killer on my machine, so this PR's preview build is the full link check.
  • Checked every relative link, landing-page card, and sidebar entry in the changed files points to an existing page.
  • Reviewed the changed pages on a local dev server.

SME review:

  • An SME has approved this change.

DOCS review:

  • A member of the docs team has approved this change.

Merge checklist:

  • Deploy preview inspected wherever changes were made
  • Build completed successfully
  • Test have passed

…enTelemetry

Document the LogCollector openTelemetry section: exporting flow, DNS,
and audit logs and federated component metrics over OTLP, exporter auth
headers and per-exporter TLS, Collector resource overrides, and how to
turn export off.

…h logs section

The page covers metrics as well as logs and isn't tied to Elasticsearch,
so it belongs at the top level of observability.

…try to them

Move Archive logs out of observability/elastic/ next to the OpenTelemetry
guide, add OpenTelemetry to the destination lists and as a tab on the
Archive logs page, and add a commented redirect for 3.24 EP3.

Drop the "only Splunk Enterprise is supported" note: the operator posts to
any Splunk HTTP Event Collector endpoint, which Splunk Cloud Platform also
provides.
