Add bot to manage stale PRs

[bm1549]

What does this PR do?

Adds a GHA bot (written by Github) that will

• Comment on and label stale PRs as stale after 60 days of inactivity
  • This resets after any update, including comments, edits, pushes, etc
• Close PRs that are marked as stale without any action taken after 14 additional days
  • The branch will not be deleted so these can be easily re-opened

Provides the use of another label keep-open to avoid the bot check

LGTM. I'd like to see this applied to all 8 tracers. I'd also like @bengl to review as well.

[bengl]

While I see time-based auto-closing as generally an anti-pattern, it's worth seeing whether the benefits outweigh the costs, and we're not going to know that until we try it.
