Wikik documentation should separate read-only parameters from the parameters table

[johlju]

I suggest we add another table for the Read-Only parameters. Since they are in a table with the header 'Parameters' it could be believed they can be used to pass in values to the resource. The type qualifier Read might not be understood for new users.

Havind this in a table with a header 'Read-Only Properties' and with the text "Properties returned from Get-DscConfiguration, or Invoke-DscResource when called with the value Get for the parameter Method."

Example here with a read-only property. https://github.com/PowerShell/xActiveDirectory/wiki/xADDomainController
