Make created docker image publicly available

[papauorg]

The docker image that is created via the build pipeline in this repo is not publicly available. I noticed that when I was trying to update the image of my brewery setup:

[+] Building 0.3s (3/3) FINISHED

Also it is not visible when viewing the repo in the browser when not logged in to github:

Please change the package settings of the docker image so it can be downloaded anonymously and so can be used by whoever wants to without a login.

Here is the github documentation on how this can be done:
https://docs.github.com/en/packages/learn-github-packages/configuring-a-packages-access-control-and-visibility#configuring-visibility-of-packages-for-an-organization

@papauorg Had to enable public option first for the org as possibility and changed it now for the repo. Can you test if it is working and report back.

@avollkopf Perfect! The images are visible in the browser and can be downloaded via docker. Thanks
