    [SPARK-36377][DOCS] Re-document "Options read in YARN client/cluster mode" 
section in spark-env.sh.template
    
    ### What changes were proposed in this pull request?
    
    Edit spark-env.sh.template for better documentation.
    
    ### Why are the changes needed?
    
    Some options  (e.g. SPARK_CONF_DIR, SPARK_EXECUTOR_CORES, etc.) are read by 
any mode but are in the "Options read in YARN client/cluster mode" that might 
confuse users, so we should separate YARN only options from others.
    
    ### Does this PR introduce _any_ user-facing change?
    
    Yes, docs changed.
    
    ### How was this patch tested?
    
    Just a manual checking.

    Closes #33604 from yutoacts/SPARK-36377.
