chore(shipyard-controller): Do not interpret absence of configurationChange property as an error (#5979)

[bacherfl]

Closes #5979

Note: The problem described in #5979 that prevented the delivery sequence was caused by a misconfiguration of the remote-exec plane helm-service. However, the missing configurationChange property should not be interpreted as an error since deployment.triggered events do not have the strict requirement of having this property.
