[FEAT]: Support for Ephemeral Resources

### Describe the need

Hello!
I'm reaching out to inquire about the potential support for ephemeral resources within the GitHub Terraform provider.
My specific use case involves creating pull requests (PRs) using this provider. I don't really need to store the PR resource in the state? Currently, I have to apply Terraform a second time to remove these resources from the state. Ephemeral resources would be a great addition, allowing resources to exist temporarily without being stored persistently.
Is there any plan to support this feature in the future?
Thank you
