Increase number of items in `.status.history` to five

[matheuscscp]

Currently we truncate to only two elements. This feature was originally designed to support the controller state machine, but it can also be about observability. We should evaluate if it's feasible increasing from two to five elements without affecting the state machine logic.

Note: When using RetryOnFailure the amount is already five, since the retry state machine for this setting is much simpler. We should, however, review one more time if this is really OK and fix any potential bugs this could be causing to the action state machine.
