[Documentation - OpenTelemetry AWS Lambda] Update docs as a workaround may no longer be required

[cyrille-leclerc]

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

As this otel-js PR has been merged, we can probably simplify our documentation.

@michaelhyatt the Node.js Lambda Layer seems to have evolved with AMD64 and ARM64 layers as we can see on https://aws-otel.github.io/docs/getting-started/lambda/lambda-jsas you can see on the screenshots below . We probably also have to update this part.
