Remove stale.yml?

[Marcono1234]

This project has currently a stale.yml file, however it appears probot-stale is not actively maintained anymore, see probot/stale#385.

Though in general, all these stale bots can be disruptive for contributors (see for example actions/stale#719 and linked issues and discussions), so maybe unless you really find yourself in a situation where there are too many outdated issues / pull requests in the future, would it make sense to remove the stale bot?

Also, stalebots are highly controversial. Perhaps it's best not to include it in an endorsed Github OSPO template? I doubt incurring that controversy is going to make it easier for a company to get internal buyin for its OSPO.

Thanks both for the input. I do use stalebot on a lot of things personally and this just got carried over and forgotten. I'll remove it. No need to have stalebot in here.
