arm64 docker image

[morganchristiansson]

The docker images on https://quay.io/repository/roboll/helmfile do not support multi-arch / arm64.

I realize you offer arm64 binaries already and I can build arm64 myself but would be nice if official image had arm64. I can have a go at updating circleci in a PR?

Building docker image on arm64 currently fails on installing helm-diff plugin.

docker buildx build \
        --platform=linux/amd64,linux/arm64 \
        -t quay.io/work/helmfile:v0.142.0 \
        .

Lack of arm64 has been reported in several issues in helm-diff repo
https://github.com/databus23/helm-diff/issues?q=arm64

[morganchristiansson]

helm-diff has released 3.2.0 with arm64 support https://github.com/databus23/helm-diff/releases/tag/v3.2.0

Had a go at updating build scripts in PR #2040
