Invalid target type in user doc

[rene00]

From example in https://registry.terraform.io/providers/PagerDuty/pagerduty/latest/docs/data-sources/user:

resource "pagerduty_escalation_policy" "foo" {
  name      = "Engineering Escalation Policy"
  num_loops = 2

  rule {
    escalation_delay_in_minutes = 10

    target {
      type = "user"
      id   = data.pagerduty_user.me.id
    }
  }
}

I believe type should be user_reference and not user based off https://registry.terraform.io/providers/PagerDuty/pagerduty/latest/docs/resources/escalation_policy#type
