[Documentation] Updating WAF policy using name as a parameter (instead of resource ID) fails

### Describe the bug

In the documentation link: Documentation states otherwise https://docs.microsoft.com/en-us/cli/azure/network/application-gateway/http-listener?view=azure-cli-latest#az_network_application_gateway_http_listener_update

For HTTP listener update, in the optional parameters it says
**"--waf-policy
Name or ID of a web application firewall policy resource."**

But when we try with Name it fails, we need to update the documentation and remove the "Name" part.
