fix: query resource group under giving subscription id

[bcho]

Description

When there are multiple subscriptions under the local azure account, the setup-gh command would fail to discover the correct resource group with error like this:

Error: resource group not found

This is because the resource group validation logic is expecting 1) the local azcli has fetched all subscriptions 2) the resource group is created under the active subscription. However these assumptions are incorrect when running with command like this:

$ draft setup-gh -s <my-sub-id> -g <my-rg-name>

To get the resource group correctly, this pull request added --subscription parameter on the query command. I also enhanced the error message a bit to provide more details on missing resource group error.
