Fix typo when calling ansible.command_local

[ruizink]

This should fix the ansible.sh shell provisioner error on chatops box:

==> chatops: ERROR: 400 Client Error: Bad Request
==> chatops: MESSAGE: Additional properties are not allowed ('module-name' was unexpected) for url: http://127.0.0.1:9101/v1/executions

Thanks! :+1:

It's oversight after changing ansible integration pack. Eventually, we replaced all - with _ in parameter names in v0.2.

I'm surprised it still works after almost 1 year. Thanks to your contribution, it's reminder for me to revise tutorial and demo to update all instructions.

Pretty a lot drastically changed in StackStorm since this Ansible demo:

• new chatops in v1.2.0
• new installation way with packages
