Response of keyvault set secret includes secret value by default

### Describe the bug

The default behavior of `az keyvault secret set` will return the secret value in plain text. It is dangerous. In our scenario, we have a script to generate secret then save into kv. We think the secret only exists in memroy and kv, but actually is printed and logged.

### Related command

az keyvault secret set --subscription xxxx --vault-name xxx--name test-secret --value '123'

### Issue script & Debug output

No error in script/cmd

### Expected behavior

can we make `--output none` as default
