Notify chrome update only when chromium is cached
What does this MR do and why?
I noticed that chromium version actually lags behind chrome by at least a few days. Notify about version update only when chromium is updated:
- to avoid duplicate notification, once on chrome update and second time on chromium update
- we also can't update the version in image builds before both packages are present, so it's better to notify when chromium is up to date as well
