Comment 2 for bug 1968919

Just to record other instances of restart prompts that happen on a regular update. I haven't verified if they happen on do-release-upgrade, but if they do, I think it's the same case.

- glibc update: there is a prompt about restarting services
- docker update: it also prompts about letting it be restarted or not, because containers can/will die if docker is restarted.
