`update_processor_class` has wrong types

Is this a support request?

No

Describe the bug

When using Files.new_data_source as a update_processor_class with my Config, as mentioned in the example, mypy throws an error :

error: Argument "update_processor_class" to "Config" has incompatible type "object"; expected "Callable[[Config, FeatureStore, Event], UpdateProcessor] | None"  [arg-type]

I believe this is due to the wrong types being specified in either update_processor_class or the return type of new_data_source.

python-server-sdk/ldclient/integrations/__init__.py

Lines 205 to 221 in dc59c94

	class Files:
	"""Provides factory methods for integrations with filesystem data."""
	@staticmethod
	def new_data_source(paths: List[str], auto_update: bool = False, poll_interval: float = 1, force_polling: bool = False) -> object:
	"""Provides a way to use local files as a source of feature flag state. This would typically be
	used in a test environment, to operate using a predetermined feature flag state without an
	actual LaunchDarkly connection.
	To use this component, call ``new_data_source``, specifying the file path(s) of your data file(s)
	in the ``paths`` parameter; then put the value returned by this method into the ``update_processor_class``
	property of your LaunchDarkly client configuration (:class:`ldclient.config.Config`).
	::
	from ldclient.integrations import Files
	data_source = Files.new_data_source(paths=[ myFilePath ])
	config = Config(update_processor_class=data_source)

python-server-sdk/ldclient/config.py

Lines 379 to 383 in dc59c94

	@property
	def update_processor_class(self) -> Optional[Callable[['Config', FeatureStore, Event], UpdateProcessor]]:
	return self.__update_processor_class

Expected behavior
There should be no type error when using the method as in the documentation.

SDK version
9.12.0
