Steps to Reproduce

Specify metro in uppercase as it's defined in the documentation at
List of metros: https://deploy.equinix.com/developers/docs/metal/locations/metros/#metros-quick-reference

Works fine in provider 1.24.0. If a put metro in lower case, then I get the error:

╷
│ Error: Provider produced inconsistent result after apply
│
│ When applying changes to equinix_metal_vlan.vlans[0], provider "provider[\"registry.terraform.io/equinix/equinix\"]" produced an unexpected new value: .description: was null, but now cty.StringVal("").

Could workaround above bug by adding description = "" to the equinix_metal_vlan resource, but according to the docs at https://registry.terraform.io/providers/equinix/equinix/latest/docs/resources/equinix_metal_vlan#description , it's supposed to be an optional attribute.
