LGTM.

Do you want to remove the unused http client based entries from SemanticConventions.cs?

@rajkumar-rangaraj Will do separately: #5071

[utpilla]

Could you hardcode the kind to ActivityKind.Client here as well similar to how you have done it for the webrequest one?

in web request we cannot rely on activity being non-null always. here we can, but I can update this one as well later.
