fix: mark these attributes as computed because they are defaulted as lists

[brandonc]

Description

Previously, these attributes would not be added to the state but be defaulted by the API, which would be displayed as a drift

Testing plan

1. Use this config to create a new workspace:

provider "tfe" {
  hostname = "HOSTNAME"
}

terraform {
  required_providers {
    tfe = {
      version = "~> 0.27.0"
    }
  }
}

resource "tfe_workspace" "test" {
  name               = "my-cool-workspace"
  organization       = "hashicorp"
  global_remote_state = false
}

After applying this, change the name of the workspace and plan the change.

Previously, you'd see this warning:

Terraform detected the following changes made outside of Terraform since the last "terraform apply":

  # tfe_workspace.test has changed
  ~ resource "tfe_workspace" "test" {
        id                            = "ws-RGzPjmdTVvADZpdb"
        name                          = "my-cool-workspace"
      + remote_state_consumer_ids     = []
      + trigger_prefixes              = []
        # (12 unchanged attributes hidden)
    }

After applying this change, you'll notice that the warning does not show because the state has stored the computed value, which matches the default that the API generates:

$ terraform state show tfe_workspace.test
# tfe_workspace.test:
resource "tfe_workspace" "test" {
    allow_destroy_plan            = true
    auto_apply                    = false
    execution_mode                = "remote"
    file_triggers_enabled         = true
    global_remote_state           = true
    id                            = "ws-cszmfpgBQYCbQGcx"
    name                          = "my-cool-workspace"
    operations                    = true
    organization                  = "hashicorp"
    queue_all_runs                = true
    remote_state_consumer_ids     = []
    speculative_enabled           = true
    structured_run_output_enabled = true
    tag_names                     = []
    terraform_version             = "1.1.4"
    trigger_prefixes              = []
}
