bug: `generate_from_file_object` doesn't work on file objects without `.name` attribute

[VolkerH]

The generate_from_file_object function has the arguments schema_file: FileLikeType and result_file: FileLikeType with FileLikeType = Union[TextIO, TextIOWrapper, FileIO].

However in https://github.com/coveooss/json-schema-for-humans/blob/178c7b1527b059b3ffe4e83c827fc8774b495aa0/json_schema_for_humans/generate.py#L93 the code tries to access the property .name of result_file. However TextIOBase objects don't have a .name attribute.

Example code like this

schema_file_object = StringIO(json.dumps(Criterion.model_json_schema()))
result_file_object = StringIO()

generate_from_file_object(schema_file=schema_file_object,  result_file=result_file_object)

results in the following error.
