Description

A lot of code imports semantic conventions attributes from opentelemetry.semconv.trace.SpanAttributes instead of the preferred opentelemetry.semconv.attributes and opentelemetry.semconv.incubating.

This PR refactors the semantic conventions to use the new stable attribute modules instead of the deprecated SpanAttributes class.

Updates to instrumentation code:

• Replaced references to SpanAttributes.HTTP_URL with HTTP_URL in response_hook and _instrumented_open_call methods for semantic convention compliance. [1] [2]

Updates to test cases:

• Updated test cases in test_urllib_integration.py to use the new constants (HTTP_METHOD, HTTP_URL, HTTP_STATUS_CODE) instead of SpanAttributes. This change affects multiple test methods, including test_basic, test_not_foundbasic, and others. [1] [2] [3] [4] [5] [6] [7]
