This worked for me, basically using the same tool that appears to be used by the repo to build the binaries.

1. Install golang https://go.dev/doc/install
2. Install goreleaser brew install goreleaser, close/reopen terminal to refresh env vars to reflect these installs
3. Git clone the repo locally and run git tag 4.9.1 (or whatever the latest version is), the git tag is needed because otherwise goreleaser complains about the tags used in repo not matching semver
4. in project root goreleaser build --single-target, this will create kubectl plugin binary in /dist/ingress-nginx_darwin_arm64/
5. In project root, run ln -s $PWD/dist/ingress-nginx_darwin_arm64/kubectl-ingress-nginx /usr/local/bin/kubectl-ingress-nginx so that kubectl can find the plugin binary (assuming that /usr/local/bin is in your $PATH)

That being said, given the goreleaser config includes darwin/arm64, the binary might already be getting built automatically, I just don't know where to find it. I looked in the release archive files and found only the source code or chart files, no plugin binary.

git clone https://github.com/kubernetes/ingress-nginx
cd cmd/plugin
go build
# Better move it to ~/.krew/bin/kubectl-ingress_nginx if you have krew installed.
# ATTENTION: The plugin name requires `-` to be replace with `_`!
sudo mv plugin /usr/local/bin/kubectl-ingress_nginx

Can we please get an official release? And also get it updated in krew? The krew version is 4 years old!
