ci: float setup-node to v4 to avoid act_runner cleanup race

act_runner v0.3.1 occasionally cleans the action checkout dir between
the main and post step; v4.0.4's post step then errors on the missing
.gitignore ("remove ... .gitignore: no such file") and fails the job.
Floating to v4 picks up the more defensive cleanup in v4.1+.
