ECOPROJECT-4246 | fix: fixed complexity scores for win server

The OS name in the inventory is taken from the "VMware Tools" column, and fallsback to the "config. file" column.
This means that there can be a big variation on OS names - which can cause the classification map to fail.

This is a quick patch for specific misclassifications, and further fixes are probably needed in the inventory creation.
