Failed system tests due to KeyError

[juliamagan]

Description

During the release of the system tests for 4.8.0 Beta 1, carried out in wazuh/wazuh#21787, it was found that most of the tests failed due to a KeyError. You can see the attached reports here.

These tests are dependent, and some may not have failed explicitly because of the KeyError but may be affected by a previous KeyError.

We should fix this error and check that all system tests pass as expected.

KeyError was produced by bug reported here #4936
Fix seems to be solved here

However, it seems it is failing in get_host_variables method. Currently testing fix
