Represents a migration step that updates the database schema or data from one
version to another.
The update logic is encapsulated in the performe method, which must
be implemented by subclasses. Updates can be chained by setting a
successor via setNext. The update method runs the current
step, persists the new version and then recursively triggers the next step.
