DEPRECATED. Completes a legacy alert index migration. Do not automate against this in new code. WARNING: Finalizing swaps read aliases; confirm the migration has finished successfully before calling.

Finalize successful migrations of detection alerts. This replaces the original index's alias with the successfully migrated index's alias. The endpoint is idempotent, so you can poll until a migration finishes and then call this operation once.
