chore: stale bot should make a comment, also change day until stale to 60 days

[Boshen]

Summary

It was brought to me that labeling anything as stale without context is invasive, this updates the bot to leave a comment on why a particular issue / pr is marked as stale.

• Increase the time before issues and pull requests are marked as stale from 30 to 60 days (daysUntilStale option in link)
• Exclude issues with the label "tracking issue" from being marked as stale (exemptLabels option in link)
• Customize the messages for issues and pull requests when they are marked as stale (markComment option in link)
  • For issues, ask the author or participants to leave a comment if the issue is still relevant and provide any new information (markComment.issues in link)
  • For pull requests, ask the author to leave a comment if the pull request is still ready for review and merge (markComment.pullRequests in link)
  • Apologize for the lack of prioritization and acknowledge the potential frustration of the stale bot in both messages (markComment.issues and markComment.pullRequests in link)
