The existing npm-specific `unpublishSafe` setting will be removed and migrated instead to use `stabilityDays` (3). The `renovate/unpublish-safe` status check is also deprecated and the existing `renovate/stability-days` will be used instead.
Closes#5265
BREAKING CHANGE: The status check `renovate/unpublish-safe` will be replaced with `renovate/stability-days`. Please migrate any branch protection rules if you were relying on `renovate/unpublish-safe`.
