terraform-providers.fly: deprecate provider

Fly.io will no longer maintain their terraform provider as of
10/24/2023 and doesn't recommend using it anymore:

https://github.com/fly-apps/terraform-provider-fly/commit/9d4be5a3010aa94ecdff6ee1a1cbf49b804511d0

This PR deprecates the provider in nixpkgs.
