[Reference feedback]: CLI command to initiate adhoc backup documented to have rule name as required and others are optional which seems to be wrong

### Type of issue

Other (describe below)

### Reference command name

Command I used

```
az dataprotection backup-instance adhoc-backup \
--rule-name "$BACKUP_POLICY_DEFAULT_RULE_NAME" \
--resource-group "$VAULT_RG" \
--vault-name "$VAULT_NAME" \
--name "$BACKUP_INSTANCE"
```

I validated the parameter passed to this command and all are valid. Please advice which parameter is having issue. I tried to re-run this command with debug enabled after some time and still getting the blocked error message. I will update the debug log once Azure unblocks me.

This is so annoying that the error message are not providing any assistance.

### Feedback

As per the documentation the ad-hoc backup command requires only the rule name and other parameters are marked as optional. The command doesnt work with just the rule name and the doc confuses even more.

I am using azure cli to trigger the adhoc backup and getting below error where it doesn't provide any clue which input has the issue.

```
(BMSUserErrorInvalidInput) Input provided for the call is invalid
Code: BMSUserErrorInvalidInput
Message: Input provided for the call is invalid
Additional Information:Type: UserFacingError
Info: {
"message": "Input provided for the call is invalid",
"recommendedAction": [
"Please check the required inputs"
],

"isUserError": false,
"properties": {
"ActivityId": "a58d1782-0fdc-11f0-a975-4689437afdb3"
}
}
```
On repeated attempts now ended up being blocked with below error message

```
(CloudDosTimeboudLimitReached) The operation is blocked, as a security precaution, since multiple attempts were made beyond an internal limit.

I am trying to take a backup of the Azure postgresql flexible server and could trigger a backup from Azure portal.

Command I used

```
az dataprotection backup-instance adhoc-backup \
--rule-name "$BACKUP_POLICY_DEFAULT_RULE_NAME" \
--resource-group "$VAULT_RG" \
--vault-name "$VAULT_NAME" \
--name "$BACKUP_INSTANCE"
```
