AZ Module does not find the class module when trying to execute Update-AzRoleManagementPolicy cmdlet

### Description

I am trying to update Azure PIM role policy settings with Update-AzRoleManagementPolicy since this seems easier than working with ARM templates. However, when I go to execute the examples found here https://docs.microsoft.com/en-us/powershell/module/az.resources/update-azrolemanagementpolicy?view=azps-8.0.0 they do not work and throw an error that the class RoleManagementPolicyExpirationRule cannot be found. I have tried this both in my Azure gov and public tenants with the same results.

### Issue script & Debug output

```PowerShell
$scope = "/subscriptions/38ab2ccc-3747-4567-b36b-9478f5602f0d/"
$expirationRule = [RoleManagementPolicyExpirationRule]@{
isExpirationRequired = "false";
maximumDuration = "P180D";
id = "Expiration_Admin_Eligibility";
ruleType = [RoleManagementPolicyRuleType]("RoleManagementPolicyExpirationRule");
targetCaller = "Admin";
targetOperation = @('All');
targetLevel = "Eligibility";
targetObject = $null;
targetInheritableSetting = $null;
targetEnforcedSetting = $null;
}
$rules = [IRoleManagementPolicyRule[]]@($expirationRule)
Update-AzRoleManagementPolicy -Scope $scope -Name "33b520ea-3544-4abc-8565-3588deb8e68e" -Rule $rules
```
