tools: merge stalebot

(Ref: nodejs/admin#860 (comment)

This PR makes the following changes to the stalebot:

1. Merges the issue stalebot and the pr stalebot into one
2. Reduce the time from 6 months to 2 months (and the stale->close time from 1 month to 2 weeks)
3. Uses the latest version of stalebot (not @mhdawson's fork)
4. Add more links to the message.

Note

This will affect open issues/PRs already, so we should go through those.

nodejs/admin#860 (comment) suggests to do it in the help repo.

I'm aware, I also think it should be applied to both.

If we have a PR that we know about, We usually mark it as 'never-stale', or we will be commenting/fixing/implementing it. I think this change will help with closing out the stragglers with no activity.

For reference, 2 months back is the last 10 pages of activity in our Issues tab. There are in total 63 pages currently, meaning 53 pages of issues will be marked as stale and in two weeks with no further updates be closed. The last 5 pages of activity in PRs would be within the allowed window, with 23 pages total meaning that 18 pages of PRs would be closed.

Your right. Let's start with the help repo and work from there. Closing here (See the help repo pull)
