Joint venues are not display in order on the event page

[mjpost]

The joint.yaml file for EMNLP 2021 lists the workshops in one order, but they are displayed in another order. Where this matters is that it would be nice if Findings were moved to the top of the list. How much work would this be to adopt the display ordering from the joint.yaml file?

That logic should go in create_hugo_yaml.py where the SortedVolume object is defined. If we don't want to hardcode it, one possible modification could be sorting venues that have toplevel: true in venues.yaml before those that don't. I don't think joint.yaml should factor into this at all.
