Ensure that 'Unattached disks' are encrypted in Azure Managed Disk

Azure Managed Disk storage should be encrypted to protect sensitive information. It is considered best practice to encrypt data at-rest in any environment that supports it, especially as it is often required for certain compliance frameworks or industry regulations.

Set 'enabled' in 'encryption_settings' to 'true' to ensure data at rest in Azure Managed Disk remains encrypted, thus reducing risk of data leak.
