Change npm rls workflow to include drafts

We need to adjust the npm workflow. Currently if you create a *draft* release in GitHub and publish it later, the npm workflow is not triggered. (its only triggered when we skip the draft and just publish right away)

I think we can use `[published]` instead of `[created]` to trigger the workflow in both cases at the correct time (once the release is finalised) but im not 100% sure
