path_to_inline_values not actually supported in tanzu-package-installer

[dsputnikk]

Describe the bug

I'm using:

Terraform v1.8.4
on linux_amd64
+ provider registry.terraform.io/vmware/tanzu-mission-control v1.4.4

I have a resource like this:

resource "tanzu-mission-control_package_install" "package_install" {
  name      = var.package_name
  namespace = var.namespace

  scope {
    cluster {
      name                    = var.cluster_name
      provisioner_name        = var.provisioner_name
      management_cluster_name = var.management_cluster_name
    }
  }

  spec {
    package_ref {
      package_metadata_name = var.package_name

      version_selection {
        constraints = var.package_version
      }
    }
    path_to_inline_values = var.inline_values
  }
}

However terraform plan comes back with:

└─[$] <> terraform plan            
╷
│ Error: Unsupported argument
│ 
│   on tkg-packages/main.tf line 21, in resource "tanzu-mission-control_package_install" "package_install":
│   21:     path_to_inline_values = var.inline_values
│ 
│ An argument named "path_to_inline_values" is not expected here.

THe only docs I've found is this:

https://github.com/vmware/terraform-provider-tanzu-mission-control/blob/d9cc1f4e9d7abed257b2a0d97ed41de16c83580e/docs/resources/package_install.md

which clearly seem to state it should be there. And I'm on the latest provider.

Reproduction steps

1. Attempt to provision via terraform a package resource
2. Follow docs on using path_to_inline_values
3. Error ...

Expected behavior

terraform plan should be aware this is a legitimate value?
