[stalebot] don't close the issue if the stale label is removed

[yiyixuxu]

currently, our StaleBot isn't working as expected:

1. it does not re-open issues - it is supposed to open the issue if someone other than Stalebot commented but it does not do that
   • if you go through our staled PR you can find lots of examples use self.device #6595
2. it will close an issue even if we had remove the "stale" label manually, e.g MotionAdapter.from_single_file #6248 (comment)

However, I think the expected behavior of the StaleBot to automatically re-open an issue after someone comments is a little bit questionable. e.g., if we leave a comment asking, "Can we close this now?" - it will trigger the StaleBot to reopen the issue. for example, here #6695

Maybe we should come up with a special spell (instead of any comments) for the StableBot to go away? cc @sayakpaul think you might be interested as a harry potter fan

The docs for this PR live here. All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.

this will always be False so this code block is never executed

Thanks for raising this up.

I think it's common practice for a StableBot to always re-open a thread when someone comments no matter what the comment comprises. I think that makes sense because in this case, we're asking the OP if we should close the issue. There might be cases, where we would close threads because of inactivities.

I think the faulty behavior you mentioned in the PR descriptions is already being fixed with the changes here, no? If so, I think that should suffice.

@BenjaminBossan what are your thoughts here since you had recently discovered a Stalebot bug IIRC.

[BenjaminBossan]

I don't really have any experience with stalebot. The bug I had reported was just a dependency issue, not related to the stalebot logic :-) Regarding the discussion, I can see arguments for both approaches, I'd probably just try the change and revert it if it is getting annoying.
