    [KYUUBI #7160] Use single try-with-resources blocks in docs example
    
    Gets rid of the nested try-with-resources blocks. Improves legibility 
slightly.
    
    ### Why are the changes needed?
    Make the example code just a bit nicer.
    
    ### How was this patch tested?
    It still compiles. I created a simple (maven) project using only these two 
java files.
    
    ### Was this patch authored or co-authored using generative AI tooling?
    No
    
    Closes #7160 from jagij/patch-1.
    
    Closes #7160
