fix(instrumentation-http): iterating through the OTEL_SEMCONV_STABILITY_OPT_IN content instead of the entry indices

[omarHassane]

Which problem is this PR solving?

Issue: Setting the OTEL_SEMCONV_STABILITY_OPT_IN environment variable doesn't do anything.
Bug: In the http.ts line 112 the for loop iterates through getEnv().OTEL_SEMCONV_STABILITY_OPT_IN but the since it's using in the value of entry would be the indice of the element in the array (0,1,..) not the value.
Fix: Using of instead iterates over the values themselves.
