Support Mac M1

[cjyar]

https://github.com/IronCoreLabs/recrypt-node-binding/runs/6751924442?check_suite_focus=true seems to indicate that we need to support arm64 on Mac:

dlopen(/Users/ironcore/actions-runner/_work/recrypt-node-binding/recrypt-node-binding/bin-package/index.node, 0x0001): tried: '/Users/ironcore/actions-runner/_work/recrypt-node-binding/recrypt-node-binding/bin-package/index.node' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '/usr/local/lib/index.node' (no such file), '/usr/lib/index.node' (no such file)

Hopefully just add arm64 to the build matrix.

Should be fixed as part of #100. The setup-node action takes an optional architecture parameter that we weren't passing, so it was defaulting to x86_64 for all of them. I added arch: arm64 to the necessary parts of our build matrix and used it for the setup-node action.
