Updates to PRs linked to an issue should clear the stale attribute

The problem

1. actions/stale said an issue was stale https://github.com/primer/view_components/issues/1033#issuecomment-1229120056 and marked it as stale https://github.com/primer/view_components/issues/1033#event-7271587943
2. I made a PR that would close the issue https://github.com/primer/view_components/issues/1033#ref-pullrequest-1353408921
3. The bot did not remove its stale marker
4. I had to add an extra comment to the issue: https://github.com/primer/view_components/issues/1033#issuecomment-1230436001

The solution

Ideally the bot should be able to recognize that a PR exists and is linked to the issue and remove the stale annotation. As stale-bot runs on a schedule, it can have access to pull requests and can therefore check to see if there are stale-issues with linked PRs and then check to see if those PRs have been touched since it last ran, and then remove the stale notice.

No files or tests are named. Start by tracing the scheduled stale-bot run and how it detects linked pull requests and recent PR activity. Done means a stale issue with a linked PR is cleared when that PR has changed since the previous run, without requiring an extra issue comment.
