Improve version bump script to also handle SNAPSHOT to RELEASE

Currently the version bump script supports the following 2 goals:

1. The goal of this script is to:
2. 1.) take all x.y.z-Helium versions to x.y.(z+1)-SNAPSHOT and
3. 2.) take all x.y.z-SNAPSHOT versions to x.(y+1).0-SNAPSHOT

We should generalize this script more so that it supports the case of going from a SNAPSHOT to a RELEASE too.
