Reduces timeouts from 10 minutes per test down to 2 minutes and changes one log.error to log.debug to avoid spamming cloud servers (#125432) (#125441)

## Summary

Fixes https://github.com/elastic/kibana/issues/125319

Reduces timeouts from 10 minutes per test down to 2 minutes and changes log.error to log.debug to avoid spamming

I test this by making a failing test here:
```
x-pack/test/detection_engine_api_integration/security_and_spaces/tests/aliases.ts
```

By increasing `await waitForSignalsToBePresent(supertest, log, 4, [id]);` from `4` to `5`....Then I watched the logs and timed it to ensure it doesn't take 2 minutes.

I did this by running the server:
```sh
 node scripts/functional_tests_server.js --config test/detection_engine_api_integration/security_and_spaces/config.ts
```

And then running the client:
```sh
 node scripts/functional_test_runner.js --config test/detection_engine_api_integration/security_and_spaces/config.ts --include test/detection_engine_api_integration/security_and_spaces/tests/aliases.ts
```

If we start to see flake again on the regular build servers we might have to slightly increase this number again. If this doesn't allow failing servers to fully complete we might need to also decrease this number further or we might need to make this more configurable.
