 Span attributes now use the shared `@sentry/conventions` package under the hood.
 The deprecated `semanticAttributes` re-export was removed. Import span attribute constants from `@sentry/core` directly.
-`SEMANTIC_ATTRIBUTE_SENTRY_SOURCE` (`sentry.source`) was removed. Use the `sentry.segment.name.source` attribute instead. The SDK does not export a constant for it, import `SENTRY_SEGMENT_NAME_SOURCE` from `@sentry/conventions/attributes` or use the string.
