devshell.nix incompatibility with aarch64

[tcmulcahy]

Line 28 of https://github.com/tadfisher/android-nixpkgs/blob/main/template/devshell.nix#L28 refers to android-studio, which isn't supported on aarch64. This results in confusing error messages for people on aarch64 (i.e. anyone on a M* Mac). (These can be fixed by removing android-studio manually, but it's not very discoverable that you need to do that)
