~~I wonder if this is an issue with the API not the python sdk...~~ Nevermind. I see the problem.

The maintainers would need to update https://github.com/databricks/databricks-sdk-py/blob/c2367af3bf4d5d3636aab8ea8672e48d5539d36b/databricks/sdk/dbutils.py#L16 by adding the `is_dir` field in the named tuple and respectively update https://github.com/databricks/databricks-sdk-py/blob/c2367af3bf4d5d3636aab8ea8672e48d5539d36b/databricks/sdk/dbutils.py#L57 by passing `f.is_dir`
