Logstash health_check API is always skipped regardless of mode

Diagnostics version: `9.3.1`

The logstash health report is always skipped, supposedly, due to its `mode` despite running in `full` mode. Subsequent APIs do get collected.
`WARN co.elastic.support.rest.RestEntryConfig - logstash_health_report was bypassed due to mode`

---

Based on the logic defined here, this should note get skipped with `full` mode
