nsx_edge_transport_node fails to create edge when using standard_host_switch with static_ip ip_assignment

[martinrohrbach]

Describe the bug

In addition to #1146 we found another problem with the nsx_edge_transport_node resource. When using a ip_assignment of static_ip for the standard_host_switch like so:

resource "nsxt_edge_transport_node" "test2” {
  description  = "edge-test"
  display_name = "edge-test"

  standard_host_switch {
    host_switch_id = "xxx"
    ip_assignment {
      static_ip {
        ip_addresses = ["xxx"]
        subnet_mask = "xxx"
        default_gateway = "xxx"
      }
    }
    transport_zone_endpoint {
      transport_zone          = "xxx“
      transport_zone_profiles = ["xxx"]
    }
    host_switch_profile = ["xxx"]
    pnic {
      device_name = "fp-eth0"
      uplink_name = "uplink"
    }
  }

  deployment_config {
    form_factor = "SMALL"
    node_user_settings {
      cli_password  = "VMware1!VMware1!"
      root_password = "VMware1!VMware1!"
    }
    vm_deployment_config {
        <redacted>
    }
  }
 
  node_settings {
    hostname             = "edge-test"
    allow_ssh_root_login = true
    enable_ssh           = true
  }
}

We get the following error when applying this to NSX-T:

│ Error: failed to create Transport Node: error parsing HostSwitchSpec schema no valid IP assignment found
│
│ with nsxt_edge_transport_node.test2,
│ on [edges.tf](http://edges.tf/) line 1, in resource "nsxt_edge_transport_node" "test2":
│ 1: resource "nsxt_edge_transport_node" "test2" {

We're not sure what happens there as we cannot see the API call that the provider send to the backend, but somehow the info in the schema is not correctly translated?

Reproduction steps

1. Create a nsxt_edge_transport_node with a static ip assignment

Expected behavior

Edge node is created with static ip assignment and no error.

Additional context

We're testing against NSX 4.1.1.0 in our test environment.
