Suggested by @sbrl to manage stale/inactive PRs

Initially, I was 👍 with that idea, but actually... PRs are just 2 pages and we can manually scan them, also most of them are from last year which isn't too old for me ;d

But yea, good to have for the future, indeed. I'll look over it for setup.

Yeah I went through everything in the backlog today so its pretty manageable right now

[sbrl]

Maybe we could set it to something like a month for the "waiting message" that asks for updates, and 3 months for closing?

[audiolion]

seems reasonable

[tunnckoCore]

yep
