ci: update external actions with Node 16 deprecation warnings

Github-hosted runners have taken a first step to transition away from Node 16,
as it is reaching end of life.  As a consequence, a large number of actions
our CI depends on have been updated to run with Node 20 instead.

This commit updates to these new versions.
