[connector/exceptions] Add trace id and span id to generated logs (open-telemetry#28670)

**Description:** <Describe what has changed.>
The current implementation generates logs from recorded exceptions in
spans, but is not possible to see which traces and spans generated those
logs. This PR adds that information to the logs

**Link to tracking Issue:** Fixes open-telemetry#24407
