Now that the feed is going to fail to download, we must take these logs into account so that the tests are not marked as failed. For example in this build, we can see that test test_first_syscollector_scan has failed because the following logs appear, which should be expected:

"manager1": {
        "ERROR": [],
        "CRITICAL": [],
        "WARNING": [
            "2024/09/12 12:41:57 wazuh-modulesd:content-updater[82704] offlineDownloader.hpp:90 at operator()(): WARNING: Error '-1' when downloading file: Couldn't connect to server."
        ]
    }

However, this is a WARNING level log, and they were disabled in #5699. Please, update your base branch and execute the tests again.
