feat(source-map-issues): Adding group id and title as attr to processing error trace item (#112387)

- The sample events should be links that take us to the corresponding
issue details
- Sending title and group id as attributes so that we don't have to 
- - 1) fetch the trace items for the event_ids and then
- - 2) fetch the full events using the event details endpoints
