`az group create` incorrectly requests `--rg-name` argument

Describe the bug In some situations, the Azure CLI requres the use of the --rg-name argument with az group create. When this argument is required, --name does not work as an alias.

This argument only works when the --name argument is refused; otherwise the --name argument is reported as required, and --rg-name does not work.

To Reproduce

• Reproduction may require a fully clean install (removal of .azure cache, uninstall Azure CLI, reinstall Azure CLI)

az interactive

az>> group create -n 'Example2' --location westus2
az group create: error: the following arguments are required: --rg-name, --location/-l
usage: az group create [-h] [--verbose] [--debug]
[--output {json,jsonc,table,tsv,yaml,none}]
[--query JMESPATH] --rg-name RG_NAME --location
LOCATION [--tags TAGS] [--subscription _SUBSCRIPTION]

az>> /home/stramer/.azure/cliextensions/interactive/azext_interactive/azclishell/_dump_commands.py:136: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.         help_entry = yaml.load(help_yaml)
az>>
az>> group create -n 'Example2' --location westus2
{
"id": "/subscriptions/07a45d58-11b5-4fd3-8cb6-12ac232d1c3f/resourceGroups/Example2", 
"location": "westus2",
"managedBy": null,
"name": "Example2", 
"properties": {
"provisioningState": "Succeeded"
},
"tags": null,
"type": null

Expected behavior az group create requires and works with the --name argument.

Additional context

• The bug seems to be triggered only while running in az interactive, and remediated by the failed YAML load.
• If --rg-name is an allowable switch, it should be an alias for --name to avoid breaking compatibility.

Actually, I think that this is most likely a bug in az interactive. I’m going to transfer the issue there and I will investigate. If it turns out to be an issue with the help system, I’ll transfer it back.

--rg-name is definitely not an allowable option. @adewaleo please take a look.
