fix: reconfigure stalebot to not close bugs

[pichlermarc]

Which problem is this PR solving?

Stalebot seems to apply stale labels to bug issues and closing them. This PR addresses that by adding bug to the exempt-issue-labels.

@pichlermarc I guess one idea to try (based on convo just had in SIG) - instead of having "exempt" labels to exempt bugs and instrumentation requests, we can have "any-of" labels, which is something we do on Honeycomb repos. This way we don't have to specifically remove a bug label if something is perhaps a misunderstanding but maybe a bug and needing info from the author.
So for example, our stalebot looks at any-of-labels: 'status: info needed,status: revision needed'

Yep I think that's a good idea. 🙂 I've been meaning to introduce a few more that may lead to an issue being automatically closed for some time now as part of a new issue triage worflow. I think we can start with information-requested and gradually expand that as we add more labels.

Would you like to open a PR @JamieDanielson? Otherwise, I'll get around to it tomorrow. 🙂
