feat(tracing)!: update tracing to use otel api (#1269)

* feat(tracing)!: migrate OpenTelemetry adapter to use otel API

Refactored the OpenTelemetry tracing adapter to follow OpenTelemetry library best practices. The adapter now uses only the OpenTelemetry API, does not modify global state, and relies on the application to configure the SDK and tracer provider. Removed legacy exporter and span processor configuration from the adapter. Updated tests to reflect the new initialization logic and ensure backward compatibility with old config parameters.
