Cannot add schedule and user as recipients on opsgenie_escalation resource

Hi there,

I've noticed a bug when tryind to add a schedule and a user to an escalation. If just the schedule is added as a recipient it works fine, if just the user is added it works fine but when both are added as recipients only the user gets added in the console despite the plan looking correct. The plan looks as if both will be added but when applied it doesn't work as expected. Following the documentation here - https://registry.terraform.io/providers/opsgenie/opsgenie/latest/docs/resources/escalation

Terraform Version

1.3.1

Affected Resource(s)

opsgenie_escalation

Terraform Configuration Files

resource "opsgenie_escalation" "escalation" {
  name        = "escalation"
  description = "description"

  rules {
    condition   = "if-not-acked"
    notify_type = "default"
    delay       = 0

    recipient {
      type = "schedule"
      id   = opsgenie_schedule.some_schedule.id
    }
    recipient {
      type = "user"
      id   = "user-id-here"
    }
  }
}

Expected Behavior

# opsgenie_escalation.escalation will be updated in-place
 resource "opsgenie_escalation" "escalation" {
        id            = "resource-id-here"
        name          = "escalation"
        # (1 unchanged attribute hidden)

      ~ rules {
            # (3 unchanged attributes hidden)

          + recipient {
              + id   = "user-id-here"
              + type = "user"
            }

            # (1 unchanged block hidden)
        }
    }

Actual Behavior

The user replaces the schedule rather than being added as an additional recipient upon a terraform apply
