refactor: semcov opentelemetry-instrumentation/src/opentelemetry/instrumentation/_semconv.py

[EzzioMoreira]

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.

The changes migrate from:

• Module Update: opentelemetry-instrumentation/src/opentelemetry/instrumentation/_semconv.py
• From opentelemetry.semconv.trace import SpanAttributes
• To specific imports from opentelemetry.semconv.schemas.* and opentelemetry.semconv._incubating.attributes.*

Key Changes:

• Updated imports in opentelemetry-instrumentation/_semconv.py to use the new attribute modules
• Schema URL Modernization: Updated schema URL handling to use the official Schemas.V1_33_0.value from opentelemetry.semconv.schemas instead of the deprecated SpanAttributes.SCHEMA_URL
