chore(seer grouping): Improve logging of Seer results (#76006)

This makes two small changes to the logs we send when getting results from Seer:

- Send the result data as JSON rather than as a list of `SeerSimilarIssueData` repr strings. (This will make it a little easier to search in GCP.)

- Include the event id when logging problematic Seer responses (ones which point to non-existent or orphan grouphashes).
