README mentions option "list-commits-exceeding-patch-set-count" for gerrit_stats.sh but it does not seem to exist

As per the title, it looks to me like the option mentionned in the README does not exist anymore.

Also, using "git log -p -S list-commits-exceeding-patch-set-count", I stumbled upon a related commit b9a5ba7 :

    Create a chart of commits that exceed n patch sets
    
    Rename the command line argument to --commit-patch-set-count-threshold in
    preparation to always make the listing occur, with some default value set.

But even trying to use "commit-patch-set-count-threshold" did not quite work for me and it looks like this was deleted with 1b08f25 :

    Add pmd to gradle check step
    
    The config file is from
    https://github.com/GoogleCloudPlatform/google-cloud-java
    with minor modifications, and licensed under Apache license.
    
    As with checkstyle, this can be run with:
    ./gradlew check
    ./gradlew clean check

I'm happy to submit a PR to update the doc if needed.
