[LogsDB] [Subscription basic] [aws_mq] Failing test daily: system test: default in aws_mq.rabbitmq_general_logs

- Stack version: maximum of either the version used in PR builds or 8.17.0 (GA version for LogsDB index mode)
- LogsDB: enabled
- Subscription: basic
- Package: aws_mq
- Failing test: system test: default
- DataStream: rabbitmq_general_logs
- Owners:
- @elastic/obs-infraobs-integrations

Failure:
```
test case failed: could not find the expected hits in logs-aws_mq.rabbitmq_general_logs-17657 data stream
```

First build failed: https://buildkite.com/elastic/integrations/builds/49410

Start with the aws_mq package's “system test: default” for the rabbitmq_general_logs data stream and inspect the failure from Buildkite build 49410. Reproduce the test with LogsDB enabled and a basic subscription, then trace why the expected hits are missing; done means the test finds the expected hits in the data stream.
