ci: fix version bump during publish

There were two issues:
- I forgot to "Configure GitHub User" before `npm version`, so it failed
  when it tried to commit the version bump.
- The version bump script didn't `set -e`, so the commit failure didn't
  interrupt the script and didn't cause a job failure.
