    [SPARK-58416][SQL][EXAMPLE] Fix wrong class name in SqlNetworkWordCount usage messages
    
    ### What changes were proposed in this pull request?
    Fixes the usage message in the `SqlNetworkWordCount` streaming examples, which printed the wrong class name (`JavaNetworkWordCount` / `NetworkWordCount`, copied from the sibling example). Corrected in both the Java and Scala versions.
    
    ### Why are the changes needed?
    A user running the example with too few arguments saw a usage line naming a different class. Every other reference in each file already uses the correct class name.
    
    ### Does this PR introduce _any_ user-facing change?
    Yes (minor): the stderr usage message now prints the correct class name.
    
    ### How was this patch tested?
    Example-only string change; verified the corrected name matches each file's class and header. No tests needed.
    
    ### Was this patch authored or co-authored using generative AI tooling?
    Generated-by: Claude Code (Opus 4.8)
    
    Closes #57622 from uros-b/example-javasqlnetworkwordcount-usage.
