Code sample expanded upon

The sample discovery script to me anyway, seemed short on a practical example that a customer could build upon, and made it harder to understand at first glance, what the script should actually be doing.

I've suggested using some code to first gather the results from the device, and then feed it into the hash, as I think it would help understanding. I've also removed the line in the output script that referenced a Microsoft employee's username - I don't think it is necessary to show the script being run, but just the actual output.

 - Is added to Intune before you create a compliance policy. After it's added, it will be available to select when you create a compliance policy with custom settings.
 - Runs on a device that receives the compliance policy. The script evaluates the conditions of the JSON file you upload to the same policy.
-- Identifies one or more settings, as defined in the JSON,  and returns a list of discovered values for those settings. A single script can be assigned to each policy, and supports discovery of multiple settings.
