ASGI instrumentation metrics don't align with the semantic conventions

[liinie]

Describe your environment

OS: (Linux, MacOS)
Python version: (Python 3.8)
Package version: (0.50b0, 0.51b0)

What happened?

the _set_http_net_host method is implemented in _semconv.py to align with Semantic Conventions (v1.30.0), enabling the extraction of server.address in opt_in mode (see semconv doc) for the http.server.request.duration metric. However, this method is never imported in the ASGI instrumentation package (see instrumentation/asgi/init.py), making the server.address attribute unavailable.
Please fix this issue or provide a workaround to extract the http server name when using http.server.request.duration metric for ASGI instrumentation.

Steps to Reproduce

opentelemetry-python-contrib/instrumentation/opentelemetry-instrumentation-asgi/src/opentelemetry/instrumentation/asgi/__init__.py

Line 219 in 139f3e5

_set_http_net_host_port,

the _set_http_net_host could be added here

Expected Result

server.address is enabled for http.server.request.duration

Actual Result

server.address doesn't work even in opt-in mode
