ssi_some: data corruption in TCP/Syslog/Unix input

### Summary

For Elastic Agent v9.2, in the TCP/Syslog/Unix input, while listening on the port, randomly messages become fragmented. Sometimes multiple messages are combined into one; other times, messages may be truncated at the beginning or end. ([Beats issue](https://github.com/elastic/beats/issues/47550))

To address this data corruption issue, a [PR](https://github.com/elastic/beats/pull/47618) was raised and merged. The fix will be available in version `9.2.2`. The affected versions are `9.2.0` and `9.2.1`; therefore, any integration using these inputs with these stack versions is also affected.

We should update the minimum required stack version to `9.2.2` once it becomes available. Or, in the meantime, we should add a note to the README of all affected integrations.
