Include arm64 builds in release assets

[pzcfg]

#157 added a go-junit-report-$(VERSION)-darwin-arm64.tar.gz build, but it doesn't seem to be in the release assets

This is causing tools like rtx to fail to install go-junit-report on arm64

% rtx i
Arch 'arm64' not supported!
Arch 'arm64' not supported!
rtx go-junit-report@2.0.0 [ERROR] ~/.local/share/rtx/plugins/go ✗ 0s rtx ~/.local/share/rtx/plugins/go-junit-report/bin/download exited with non-zero status: exit code 1
rtx Run with RTX_DEBUG=1 for more information

Could this build be included in the assets?

Unfortunately not in this repository, but my fork includes binaries for Darwin and Linux on ARM64: https://github.com/joschi/go-junit-report/releases/tag/v2.2.0
