feat(bug-prediction): Also fetch error message for get_issues_related_to_exception_type call (#97579)

- Don't just fetch the issue IDs, also return the error message (eg:
`OutboxDatabaseError: Failed to process Outbox, TEAM_UPDATE due to
database error`)
- This will be used by the bug prediction tool when a user's repo does
not have seer setup so they can not retrieve the seer summaries from the
issue IDs, so we will at least provide the error message to the AI agent
to look at instead of nothing

### Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated
in the State of Delaware in 2015 as Functional Software, Inc. and is
gonna need some rights from me in order to utilize my contributions in
this here PR. So here's the deal: I retain all rights, title and
interest in and to my contributions, and by keeping this boilerplate
intact I confirm that Sentry can use, modify, copy, and redistribute my
contributions, under Sentry's choice of terms.
