update dependencies

This is a cherry pick of the updates I did on https://github.com/bingothon/bingosync/commits/bingothon-fork, which runs at https://bingosync.bingothon.com/ (on python 3.8)

Thanks for sending this, it's very helpful compared to having to read through the release notes to figure out what might have broken 😅

I don't have a great setup for deploying disruptive updates right now unfortunately, so I'll wait to merge this until I've set aside some explicit downtime.
