An alternate solution is to set no_proxy = '*', which is the fix used by two other nixpkgs: check-jsonschema, pip-tools.
So, for consistency, let's switch to that solution.

Also, I don't quite understand why this should break only on aarch64-darwin. From the bug reports (python, pytest-parallel, cython), this seem to be a macos-wide issue. But hydra builds are fine for x86_64-darwin until the recent failure - which doesn't seem to be this issue. Might as well depend on the version of macOS running on these build systems.

Sounds good. I tested it and the no_proxy solution seems to work as well. I changed the PR to use this solution.
