There are new bugfix updates for both of the Gerrit images we are
building. Bump up to these new releases. The delta between these updates
and what we are already running should be quite small since we just
updated updates recently which will update the main gerrit repo off of
stable branches. Many plugins are fixed to tags but many of those simply
get retagged with new versions. There are some exceptions to this like
the codemirror-editor plugin though.
Overall though should be a straightforward update.
