devops: try using another Github Actions event to trigger releases (microsoft#1931)

The [official
documentation](https://help.github.com/en/actions/language-and-framework-guides/publishing-nodejs-packages#publishing-packages-to-the-npm-registry)
suggests using `created` event, but it didn't work for us.

As someone mentioned on [github
community](https://github.community/t5/GitHub-Actions/Workflow-set-for-on-release-not-triggering-not-showing-up/m-p/53236#M8758),
it looks like the `created` event is actually issued when release draft
is first created.

Try using
[`published`](https://help.github.com/en/actions/reference/events-that-trigger-workflows#release-event-release)
event instead.
