Correct action command

[sarthakgupta072]

As given in the 8th step of this page https://github.com/intuit/benten/wiki/Create-BenTen-Example-conversation-in-Dialog-flow

Rename parameter name number-integer to noOfPings

Therefore instead of "noOfTimes", it should be "noOfPings" in benten-starter/src/main/java/com/example/BentenExampleAction.java

Also, since in this section

https://github.com/intuit/benten#lets-get-to-action-adding-a-new-actionhandler

the example of

https://github.com/intuit/benten/blob/master/benten-examples/src/main/java/com/example/BentenExampleAction.java

file is given, therefore that file also needed some correction.

TODO:

1. Change the pic under https://github.com/intuit/benten#lets-get-to-action-adding-a-new-actionhandle.
2. Change the code that is generated by archetype given in this section https://github.com/intuit/benten#setting-up-benten-from-binaries-recommended-if-you-want-just-use-existing-capabilities-and-add-custom-features-only-specific-to-your-organization
