release.nix: Use arm64-apple-darwin in bootstrapConfigs, not aarch64
Fix this config name for consistency with non-bootstrap platform config. This also fixes a build failure of the bootstrap tools on aarch64-darwin, where a test in LLVM 21 assumes it's spelt arm64, not aarch64. Also saves on having to rebuild LLVM just for bootstrap tools, now that the config is consistent.
