[BUG] - mgc_network_security_groups_rules always forces replacement

[Misterio77]

Describe the bug

Terraform applies always replace security group rules, even if they're unchanged.

To Reproduce

1. Use the following tf file:

terraform {
  backend "local" {
    path = ".terraform.tfstate"
  }
  required_providers {
    mgc = {
      source = "registry.terraform.io/magalucloud/mgc"
      version = "0.31.0"
    }
  }
}

resource "mgc_network_security_groups" "teste" {
  name = "teste-bug"
}

resource "mgc_network_security_groups_rules" "incoming_ssh" {
  direction = "ingress"
  port_range_min = 22
  port_range_max = 22
  protocol = "tcp"
  ethertype = "IPv4"
  remote_ip_prefix = "0.0.0.0/0"
  security_group_id = mgc_network_security_groups.teste.id
}

2. Apply. Should work as usual.
3. Apply again. You'll be prompted to replace the security group rule, like so:

OpenTofu will perform the following actions:

  # mgc_network_security_groups_rules.incoming_ssh must be replaced
-/+ resource "mgc_network_security_groups_rules" "incoming_ssh" {
      ~ id                = "243f858b-b811-42a9-93f8-02ad9f223f7d" -> (known after apply)
        # (7 unchanged attributes hidden)
    }

Plan: 1 to add, 0 to change, 1 to destroy.

Expected behavior

Rules should not be replaced if they're unchanged.

Desktop (please complete the following information):

• OS: Ubuntu 24.04.1
• Terraform: OpenTofu v1.8.8
• Provider version: v0.31.0

Additional context

This seems similar to #71.

@Misterio77 I tried to reproduce the error but couldn't get to recreate the resource, can you please validate if this still happens?
