Thomas Kosiewski 5285c12b9e chore: update terraform to 1.11.1 in nix image (#16880)
Followup PR to #16781, update the terraform version in our Nix devshell.

Additionally: 

1. Switches from DeterminateSystems/nix-installer-action to nixbuild/nix-quick-install-action -- quicker installer, reduces actions time from ~60 seconds to ~1 seconds.
2. Adds nix-community/cache-nix-action for better caching with garbage collection -- avoids unnecessary rebuilding on subsequent runs, reduces nix image build time from ~6 minutes to <4 minutes.
3. Adds nixpkgs-unstable input to use Terraform 1.11.1
