.github/workflows: update `days-before-pr-close`
Currently, the stale bot closes PRs 90 days after they are marked stale since it counts "marking a PR stale" as activity.
We really want the PRs to close after a total of 90 days, or 30 days after they are marked stale. Changing `days-before-prs-close` to 30 will fix this.
