When running "example0_1_orbits": " AttributeError: module 'pynauty' has no attribute 'Graph' ". Is this expected?

Hello, 

I'm trying to run the examples from the shimming tutorial found here: https://github.com/dwavesystems/shimming-tutorial/tree/main  

All of the installations in `requirements.txt` run fine, but the examples do not.  

When I run the first example like so: 

``` 

python -m example0_1_orbits 

``` 

I'm faced with the following error: " AttributeError: module 'pynauty' has no attribute 'Graph' ".   

Can someone please confirm that this is a legitimate bug?   

For what it's worth, I also tried the most recent version of pynauty (version 2.8.8).  This doesn't seem to change anything.

I'm using Python3.10 as suggested, and no other warnings/errors occur. 

Thanks.
