Update Hatchet to 8.0 based branch (#705)

Use Ruby 3.2 throughout.

Remove Hatchet app cleanup from end of CI workflow, because since v8.x, Hatchet now:
- Removes the apps it creates after each test runs, rather than only
  enabling maintenance mode. This occurs even if an individual test fails.
- Cleans up older apps iff it runs into the app limit. (This is only done when
  the app limit is hit, in order to prevent hundreds of unnecessary API
  requests, when test concurrency is high.)

However, leftover apps can still occur in the following cases:
- The GitHub Actions run is cancelled, or aborts in a non-clean way.
- If a Hatchet bug (or a mis-use of Hatchet by the tests) cause Hatchet
  to exit non-cleanly.
- If there is a platform incident causing the Heroku API to not be available.

Therefore, a scheduled cleanup job has been added to catch any such
leftover apps. It runs daily at 6am UTC, and can also be triggered manually
via the GitHub dashboard.

The cleanup job only deletes apps older than 10 minutes, so that it doesn't
break any in progress CI jobs.
