[LogsDB] [Stack 8.19.19-SNAPSHOT] [okta] Failing test daily: system test: oauth2-pem in okta.system

- Stack version: 8.19.19-SNAPSHOT
- LogsDB: enabled
- Package: okta
- Failing test: system test: oauth2-pem
- DataStream: system
- Owners:
- @elastic/security-service-integrations
- @elastic/sit-crest-contractors

Failure:
```
test case failed: could not find the expected hits in logs-okta.system-53717 data stream
```

First build failed: https://buildkite.com/elastic/integrations/builds/46082

Latest failed builds:
- https://buildkite.com/elastic/integrations/builds/46122

Start with the `oauth2-pem` system test in the `okta` package and compare the first failed build (46082) with the latest failed build (46122). Investigate why expected hits are missing from the `logs-okta.system-53717` data stream; done means the test finds its expected hits with LogsDB enabled.
