Remove empty implementations of describeAutomaticCapabilities()

Summary:
This has been replaced by `PolicyCodex` after D16830. Also:

  - Rebuild Celerity map to fix grumpy unit test.
  - Fix one issue on the policy exception workflow to accommodate the new code.

Test Plan:
  - `arc unit --everything`
  - Viewed policy explanations.
  - Viewed policy errors.
