OTEL_SEMCONV_STABILITY_OPT_IN not working

[msvechla]

What happened?

Steps to Reproduce

• use the latest experimental/v0.54.0 instrumentation
• add environment variable OTEL_SEMCONV_STABILITY_OPT_IN=http
• observe http client/server traces

Expected Result

Span attributes follow stable semantic conventions, e.g:

http.response.status_code: 200

Actual Result

Span attributes follow old semantic conventions, e.g:

http.status_code: 200

Additional Details

We are using the OpenTelemetry Operator and Auto-Instrumentation for NodeJS on the latest version.
The environment variable OTEL_SEMCONV_STABILITY_OPT_IN=http is set for the workloads.

You can see that the correct @opentelemetry/instrumentation-http is used with a version that should support the new semantic conventions.

Do you have any idea on what is going wrong here? Thanks a lot for your support!

Should this be of? https://github.com/open-telemetry/opentelemetry-js/blob/main/experimental/packages/opentelemetry-instrumentation-http/src/http.ts#L112

(OTEL_SEMCONV_STABILITY_OPT_IN is an array)

@marcopiraccini @dyladan yea I just had the same issue. looks like the for in is iterating through the indices.
I opened a PR to fix this:
