Correct description of the cluster field in RestorePlan

[apratimutkarsh]

Description

To avoid confusion from treating the "source cluster" as the backup cluster, this PR updates the cluster field description in the RestorePlan configuration.

This change aligns the description with the error message on docs.cloud.google.com, which clarifies it as: "the name of the target cluster to which you want to restore the backup".
