github: improve stalebot behavior/language (#12370)

1. Remove the cutesy language, it's kind of insulting. Happy to revert
this change if people feel strongly, but I _really_ don't like it when
companies do this kind of thing.
2. Extend the close delay for both PRs and issues to 72 hours. We don't
really need a response within a day and requiring a response within a
day is pretty demanding.
