ci: dont publish to NPM if the release fails

We are using the `workflow_run` action to publish a build to NPM when a
release is complete. This is also running when the release workflow
fails.

Now we are using a conditional jobs to only publish the package if the
release we successful.

I have added an extra job to fail the publish if the release fails so we
get the correct statuses and it dose not look like the publish passes
because no jobs have run.

Fixes Issue: #95
