docs: Add deprecated system_info to schema (#5168)

In some cases, `system_info` can be passed via user data or vendor data to override the system_info in /etc/cloud/cloud.cfg . While this technically can work, this is a use case we no longer support and should indicate that it is deprecated. Also remove/update examples.
