Fix CloudPath import

- Use _pathlib.CloudPath instead of cloudpathlib.CloudPath. The import here already has a bunch of logic baked in to check and fallback the pathtype if cloudpathlib isn't available.
- For the conditional logic, make use of the cloudpathlib_is_available function to step into check
- TODO: Add tests to make sure cloudpathlib functionality is working as expected
