In terraform-provider-coder v2.12.0 and the
up-coming coder v2.28 release we have removed the
requirement for the "AI Prompt" parameter, and are intending on slightly
re-designing the API of the AI task modules.
Instead of `agentapi` defining the `coder_ai_task` resource, it will
output the `task_app_id`. Consumers of the module will then be expected
to create the `coder_ai_task` resource themselves with this
`task_app_id`.
