Can't set MACOSX_DEPLOYMENT_TARGET for macos wheels

[b4stien]

Trying to build wheels for both our Linux servers and our local macOS M1 machines I struggled with the latter. maturin-action currently hard sets MACOSX_DEPLOYMENT_TARGET to 10.9 (here) which generates a ...macosx_10_9_arm64.whl wheel not installable on macOS M1 13.0.1 (no idea if it doesn't work "at all" or specifically with my project or macOS 13.0.1).

Setting MACOSX_DEPLOYMENT_TARGET to 11.0 or simply letting rustc/cargo use their default values both seem to work, generating a functional/installable ...macosx_11_0_arm64.whl wheel (setting to 11.0 and no value).

What would be the best course forward? Would you accept a PR removing the default value?

Would you accept a PR removing the default value?

Sure, MACOSX_DEPLOYMENT_TARGET is now handled in maturin so it's not needed any more.
