Update to remove a workaround recommendation

[michaelhyatt]

Motivation/summary

v0.24 of lambda layer introduced a fix that doesn't require the workaround mentioned.

The Otel AWS Lambda Node.js instrumentation documentation contains a workaround specifying OTEL_EXPORTER_OTLP_ENDPOINT waiting for open-telemetry/opentelemetry-js#2331 to be merged.

Now that the above PR was merged, the workaround is no longer required.

Checklist
