Igniter upgrader task. Invoked automatically by
mix igniter.upgrade ex_athena after the dependency is bumped;
can also be invoked directly via mix ex_athena.upgrade <from> <to>.
Each migration is keyed by the target version and runs only when
the upgrade range crosses that version. See
Igniter.Upgrades.run/5 for the routing semantics.
