    ORC-1479: Enhance examples usage message to use uber jar
    
    ### What changes were proposed in this pull request?
    The PR aims to enhance the message printed when using examples.
    From examples/target directory, if we run the command it gives an error
    
    ```
    bash-5.1$ java -jar orc-examples-*.jar --help
    no main manifest attribute, in orc-examples-2.0.0-SNAPSHOT-sources.jar
    ```
    
    If we replace the usage with following, the error goes away
    
    ```
    $java -jar orc-examples-*-uber.jar [--help]
    ```
    
    ### Why are the changes needed?
    The change shall make it more user friendly, avoiding the error message
    
    ### How was this patch tested?
    Manually tested. Following is the result post
