Description

The provider doesn't recognize the removal of the allowed_addresses attribute from the resource stackit_network_interface.

Steps to reproduce

resource "stackit_network_interface" "example" {
  project_id         = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  network_id         = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  allowed_addresses  = ["192.168.0.0/24"]
  security_group_ids = ["xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"]
}

1. Run terraform apply
2. Remove allowed_addresses attribute
3. Terraform doesn't recognize any changes

Actual behavior

The removal of the allowed_addresses attribute from the stackit_network_interface resource isn't detected.

Expected behavior

The removal of the allowed_addresses attribute from the stackit_network_interface resource is detected and changes will be applied accordingly.
