meta: add old issue stalebot
#52712 was an overly aggressive update to the stalebot, which would've lead to mass notifications being sent out to users.
This PR is a much more restrained version of that update. If an issue is older than 4 years and hasn't been updated in over 5 months, it will be marked as stale. This approach is similar to #48051 but focused on issues rather than PRs.
The 4-year threshold was chosen because it applies to only 257 issues, which seems like a manageable starting point.
Over time, I think we can unify the stalebots with the following steps:
-
(This PR) Integrate non-feature request issues into the slower stalebot process. -
Gradually reduce the END_DATE
to minimize disruption. -
Once the END_DATE
is down to 1 year, merge withclose-stale-pull-requests.yml
. -
Once the END_DATE
reaches 6 months, merge withclose-stale-feature-requests.yml
