Describe the bug

Migrate from classic alerts to built-in Azure Monitor alerts for Azure Recovery Services Vaults ARG query produce false positives.

To Reproduce

Steps to reproduce the behaviour:

1. Create a new Recovery Services Vault (without specific alerting configuration / strategy)
2. Run the ARG query
3. False positive!

Expected behaviour

This recommendation should only return Recovery Services Vault with classic alert configured. If classic alerts aren't configured, don't return the vault in the recommendation.

Additional context

The condition logic around monitoringSettings property (IF monitoringSettings isnull THEN classic alert is enabled) doesn't seem to be the best approach. Because when I configure Azure Alert and not Classic Alert for my vault, monitoringSettings still doesn't exist (so still a false positive).
