Error running flakes-based quick start on Darwin

[joaothallis]

Looks like MacOS QEMU was fixed NixOS/nixpkgs#108984

$ nix-shell
$ nix run github:fort-nix/nix-bitcoin/release
error: flake 'github:fort-nix/nix-bitcoin/release' does not provide attribute 'apps.aarch64-darwin.default', 'defaultApp.aarch64-darwin', 'packages.aarch64-darwin.default' or 'defaultPackage.aarch64-darwin'

Adding "aarch64-darwin" to supportedSystems I have this error:

$ nix run -L -v ./
