Emily 1e16e2a9c2 ci: use the PR head as <darwin> for install test
This was installing against the base branch, which causes annoying
issues when things like the state version are bumped. It’s possible
this was intentional to test the upgrade path, but it’s inconsistent
with the flake installation test and keeps breaking stuff on my
PRs. If we want to test the upgrade path then we could re‐add it
again later in a more sophisticated manner (e.g. using the example
config from the previous version).
