Our goal. as discussed in the Architecture Committee meeting held on
October 31st, 2023, is to take a more aggressive action on issues and
PRs that have been opened for a long time.
This commit is the very first step, and it's **only** targetting
**PRs**. What this action will do is:
* Mark all the PRs that have no activity for more than 180 days,
starting from May 1st, 2023, as stale.
* A message will be added, letting the contributor know that they can
simply comment on the PR in order to make it "not stale".
* If there's no activity on the PR for 7 days, the PR will be
automatically closed.
