This PR fixes site.asns and interface.tagged_vlans schema specs, but I'd expect there many more that are broken. Schema should ultimately be fixed in Netbox itself, however, it's a longer process and in order to unblock myself I've created this PR.

The configuration was regenerated using Netbox version 3.7.1. However, since the schema for object NestedASN was missing in this version, it was sourced from the latest available version (3.7.5).
