Fix stale bot for locked issues

[LysandreJik]

The stalebot has crashed once again due to the following error:

I believe it's the first time it's encountering a locked issue, hence the failure. I tested locally that it ran fine on this specific issue.

Thanks. The bot needs a lot of human help 😅

Is there only one (or just a few) issue(s) causing problem?

[LysandreJik]

Just the locked issues, I believe there's a single one here but unsure
