Prevent publish job if version does not change (#104)

## Description

<!-- Describe your changes in detail -->
<!-- Does this fix a bug, implement a new feature, etc? -->
This should prevent the publish job from failing when I don't actually
intend for it to run. Not all merges should trigger a deploy/publish.
