chore(release): bump version to 4.2.3

The migration was correct as v4.0→v4.1. Config version goes from 4.0 to 4.1
when thresholds are moved to actions. The original error was not the migration
but the ups-handler.ts bug (already fixed in v4.2.1).

User's config shows version "4.1" with actions already present, confirming
the migration ran successfully.
