Lack of clarity on the example 01

### Type of issue

Code doesn't work

### Feedback

We can see in the example command that just copy and pasting the command will not work, can we provide more details on how to build the $fp variable, and also throw in a quick way to print the rules from the collection. This is my proposal:

$fp = Get-AzFirewallPolicy -Name "FirewallPolicy" -ResourceGroupName "RGname"
$fprc = Get-AzFirewallPolicyRuleCollectionGroup -Name "DefaultNetworkRuleCollectionGroup" -AzureFirewallPolicy $fp
$fprc.Properties.RuleCollection.rules

Lets make the life for the customers easier. :)
