Although we're not on the OpenStack release schedule as such, Zed
cycle is dropping 3.6/3.7 support. This means it seems like as good a
time as any to also update ourselves to this regime. One important
dependency to think about is nodepool, but that is already >3.8 only
so we will be in sync there.
This also changes dib jobs to run using the zed template and adapts
the bindep file to handle Ubuntu Jammy.
