update panos/commit task in module example
update panos/commit task in module example

When trying to use the example at the top of the Docs page, I noticed that it crashed on the panos/commit task, which is the final task in the example. I found that if I changed the task from "commit" to "commit_config" then the commit was successful and it didn't crash
