provide multi-arch containers

[maltegrosse]

arm, arm64 and amd64 images would be helpful.

only amd64 images provided on docker hub.

upstream keycloak only supports amd64 and arm64 images, thats why I created multiarch keycloak releases, see:
https://github.com/maltegrosse/keycloak-multiarch

in order to switch to multiarch for the radius plugin, only minor changes to a github workflow/action need to be done, see:
https://github.com/maltegrosse/keycloak-radius-multiarch/blob/main/.github/workflows/container.yml#L24

Download latest multiarch docker

docker pull vassio/keycloak-radius-plugin:latest-multiarch

Run multiarch docker in dev-mode

cd docker
docker run -d --name keycloak-radius-plugin-multiarch --env-file .example.radius.env --restart=always -p 8080:8080 -p1812:1812/udp -p1813:1813/udp vassio/keycloak-radius-plugin:latest-multiarch start-dev

actually you dont have to introduce new "multiarch", just use your namespace as always. important is the build x command for multiple archs based on my debian multiarch image.

ping me if you i forget to pull the latest keycloak from upstream.

thank you for the implementation.

@vzakharchenko I updated my multi-arch images up to 19.0.1 - can you provide an updated multi-arch container of your plugin? thanks
