span_streaming path still uses start_transaction and can fail the suite

When span_streaming=True, use sentry_sdk.traces.start_span (and flush) instead of sentry_sdk.start_transaction, matching test_text_generation_streaming; otherwise the call is a NoOpSpan and emits a DeprecationWarning that the session warning recorder treats as a failure.

Evidence

• Scope.start_transaction() returns NoOpSpan() and warns "Scope.start_transaction is not available in streaming mode." when has_span_streaming_enabled is true.
• HF still creates a real streamed gen_ai span via sentry_sdk.traces.start_span when span streaming is enabled, so the assert path can pass while still recording that deprecation.
• Session fixture _capture_internal_warnings fails the suite on unfiltered sentry_sdk DeprecationWarnings; nearby HF tests already branch to traces.start_span for span_streaming=True.
