Testing

First, see that the acceptance tests passed ✅

Also tested manually:

terraform {
  required_providers {
    prefect = {
      source = "registry.terraform.io/prefecthq/prefect"
    }
  }
}

provider "prefect" {
  endpoint = "https://api.stg.prefect.dev"

  account_id   = "my-account-id"
  workspace_id = "<my-workspace-id>"

  api_key = "<my-api-key>"
}

resource "prefect_workspace" "workspace" {
  handle = "mitch-testing"
  name   = "mitch-testing"
}

resource "prefect_flow" "flow" {
  name         = "my-flow"
  workspace_id = prefect_workspace.workspace.id
  tags         = ["tf-test"]
}

resource "prefect_deployment" "deployment" {
  name                     = "my-deployment"
  description              = "string"
  workspace_id             = prefect_workspace.workspace.id
  flow_id                  = prefect_flow.flow.id
  entrypoint               = "hello_world.py:hello_world"
  tags                     = ["test"]
  enforce_parameter_schema = false
  manifest_path            = "./bar/foo"
  parameters               = jsonencode({ "some-parameter" : "some-value" })
  path                     = "./foo/bar"
  paused                   = false
  version                  = "v1.1.1"
  work_pool_name           = "mitch-testing-pool"
  work_queue_name          = "default"
}

$ go install
...

$ tf apply
...

Then I updated my config to add another field with an int and applied it, and ran a job:

Need #246 to unblock the tests.

is it a TF typing nightmare to make this a plain object, vs. a jsonecoded one?
