Incorrect documentation: 3.3.1 GET Project Files Information Service

[an-ho]

In the Example Response for files_information, the file secion looks like this:

"file": {
        "ifc_project": "3hwBHP91jBRwPsmyf$3Hea",
        "file_name": "OfficeBuilding_Heating_0003.ifc",
        "reference": "cf37bae6-0900-46be-b37f-b34754fe0b4a"
    }

However, the Schema for project_files_information_GET.json references project_file_information.json, which then references file_GET.json, which defines the field for the file name as filename and not file_name.

P.S.: It would be really nice if you could finally fix the broken schema file links in the documentation, that is super annoying.
