[pom] Change version number to allow for patches since this wraps spotbugs

While spotbugs uses semantic versioning, us doing the same does not allow for any patches.  Using this style with one extra position allows us to patch.  It will most often be .0 but in this first case, I need to release a patch to patch vulnerable library usage.
