    [SPARK-28963][BUILD] Fall back to archive.apache.org in build/mvn for older releases
    
    ### What changes were proposed in this pull request?
    
    Fall back to archive.apache.org in `build/mvn` to download Maven, in case the ASF mirrors no longer have an older release.
    
    ### Why are the changes needed?
    
    If an older release's specified Maven doesn't exist in the mirrors, {{build/mvn}} will fail.
    
    ### Does this PR introduce any user-facing change?
    
    No
    
    ### How was this patch tested?
    
    Manually tested different paths and failures by commenting in/out parts of the script and modifying it directly.
    
    Closes #25667 from srowen/SPARK-28963.
