Cannot create a new area using dnacenter_site

Prerequisites

[x] Have you tested the operation in the API directly?
[x] Do you have the latest Terraform provider version?
[x] Review the compatibility matrix before opening an issue.

Describe the bug When upgrading the Terraform provider to 1.1.0-beta it is no longer possible to create a new (non-existing) area using the resource dnacenter_site, as given below. Prior to 1.1.0-beta, it was possible to create a new area by using exactly this code.

resource "dnacenter_site" "subarea" {
  provider = dnacenter
  parameters {
    site {
      area {
        name = var.subarea_name
        parent_name = "${var.area_parent_name}/${var.area_name}"
      }
    }
  type = "area"
  }
}

With 1.1.0-beta, the error message appears telling that the "site_id" is missing. However, to create a new area, the id is not yet known and cannot be specified at this step. Screenshot 2023-04-19 at 17 13 38

Expected behavior As in prior versions, this resource should create a new area when no "site_id" is specified.
