JSON-formatted stdout is now the only supported log shape in CrewAI
Enterprise — the `CREWAI_LOG_FORMAT=json` opt-in env var is gone and
no longer needs to be configured in AMP. Removes the "Enabling JSON
output" section, the env-var setup step, the troubleshooting check,
and the `legacy text mode` comparison across the four locale copies
(`en`, `ko`, `pt-BR`, `ar`) of `docs/edge/<lang>/enterprise/guides/datadog.mdx`.
Adds a consolidated `datadog.mdx` under `docs/edge/{en,pt-BR,ko,ar}/enterprise/guides/`
covering both the Datadog Agent path (stdout JSON logs via `CREWAI_LOG_FORMAT=json`)
and the Datadog OTLP intake, with a JSON log schema reference and a ready-to-import
operations dashboard (`datadog_dashboard.json`). Reframes `capture_telemetry_logs.mdx`
to lead with OpenTelemetry as the vendor-neutral path and point readers to the new
Datadog page for that ecosystem's setup.
