Looks good to me. Thanks for changing these files around :)

Is there anything I need to pay attention to on the dependbot workflow?

It shouldn't generate too much noise, but you'll get a PR that will look something like this: cal-itp/benefits#1688. Mostly you can just approve and merge these, but if you have any questions or want me to take a look, feel free to assign me as a reviewer.
