az keyvault update returns "The Vault '<vault name>' not found within subscription"

Hi,

I have been using az keyvault update programmatically to update firewall rules when required while deploying our application. however, i am getting a vault not found error since yesterday if i run this command without --resource-group parameter. it used to work earlier but not working now. docs do not have --resource-group as required parameter.

command : az keyvault update --name --subscription --set properties.networkAcls.bypass=AzureServices --set properties.networkAcls.defaultAction=Deny --set properties.networkAcls.ipRules='[{"value":""}]'

if required parameters are indeed changed for this command, they should be reflected on docs as well; otherwise this issue should not occur.
