fix(core): Check spanArguments.op before attributes for ignoreSpans

The _shouldIgnoreStreamedSpan function was only checking
spanArguments.attributes[SEMANTIC_ATTRIBUTE_SENTRY_OP] for the op value,
but at this point in the flow, the op lives on spanArguments.op (set by
parseSentrySpanArguments which spreads StartSpanOptions). The
SEMANTIC_ATTRIBUTE_SENTRY_OP attribute is only populated later when the
SentrySpan constructor runs.

This caused any ignoreSpans pattern that filters by op (e.g.
{ op: 'http.server' }) to silently fail to match in the core/browser
streaming path. The OTel path correctly handles this by checking both:
options.op || options.attributes?.[SEMANTIC_ATTRIBUTE_SENTRY_OP].

This fix aligns the core path with the OTel implementation.
