[ISSUE] `spark.conf.get` raises Exception

[Julian-J-S]

Description
spark.conf.get raises instead of returning None or a default value according to the documentation.

Reproduction

from databricks.sdk.runtime import spark

spark.conf.get("xxxxx")  # -> Error instead of `None`
spark.conf.get("xxxxx", "my_default")  # -> Error instead of "my_default"

Expected behavior
According to the docs it should NOT raise but either return None or the provided default value.
Happens locally with databricks sdk but also in the databricks workspace in a notebook.
