Flagged Out-of-Date Comment: librdkafka1

MarsSeed flagged librdkafka1 out-of-date on 2024-02-21 (UTC) for the following reason:

Add upstream patch fix, and make this not conflict with repo's librdkafka; otherwise this breaks downstream dependents that require librdkafka v2. Or delete this, as no functioning build requires it. - https://github.com/confluentinc/librdkafka/compare/v1.9.2...v1.9.3-RC2
