release arm64/amd64 docker images automatically using Github Actions

[d-rk]

Hey,

I just added this in a fork to get an arm64 docker image. With this PR amd64/arm64 docker images will be published automatically when you push a version tag. Additionally, pre-build artifacts are available on the release page (see: https://github.com/random-dwi/smtp-gotify/releases/tag/v1.0.1)

If you want to merge this you have to add the following secrets for your repo:

• DOCKER_USERNAME: kostyaesmukov
• DOCKER_PASSWORD: password for docker hub
• GH_PAT: github personal access token (https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line)

Afterwards all you need to do a release is:

git tag v1.0.0
git push origin v1.0.0

Cheers, Dirk

Thanks for the effort, but I'm going to have to decline.

I'm not willing to use the GitHub infrastructure for building this image, nor do I want to share my dockerhub password with them.

I also don't need arm64 and I'm not willing to support it at this moment (because I cannot promise that it won't break).

If you do need an arm64 image and you are willing to support it -- that's great, but please don't involve me in it.
