Add zombienet releases for mac arm64

[pepoviola]

We should update the CI to build on this arch.

GH actions don't support macos arm64 runners at the moment. This pr cover the changes to apply when they add support.
#714

[wirednkod]

Duplicated with #434

[pepoviola]

Re-open here, since in this case is the release of zombienet itself not from polkadot.

Bumping this issue as ARMs are now supported:

Adding a matrix here should work

zombienet/.github/workflows/release.yaml

Lines 74 to 75 in 875a273

	runs-on: macos-13 # x64
	# runs-on: macos-latest is arm

Something like this:

build_release_for_mac:
    name: build_release_for_mac
    needs: build_release_for_linux
    matrix: 
        target: [ { runner: macos-13, arch: x86_64 }, { runner: macos-14, arch: arm64 } ]
    runs-on: ${{ matrix.target.runner }}
    steps:
      - name: checkout
        uses: actions/checkout@v4
        with:
          fetch-depth: 0

      # redacted for brevity

      - name: upload macos artifact
        uses: actions/upload-release-asset@v1
        env:
          GITHUB_TOKEN: ${{ github.token }}
        with:
          upload_url: ${{ needs.build_release_for_linux.outputs.upload_url }}
          asset_path: ./javascript/bins/zombienet-macos
          asset_name: zombienet-macos-${{ matrix.target.arch }}
          asset_content_type: application/octet-stream

I can open the PR if you think this is ok
