ci: refactor action to enable multi-arch builds

[MindTooth]

I reworked the action to support multi-arch builds. Notices that it did not have any and was not able to run it on my Apple Silicon. Some code is borrowed from the various actions.

Notice provenance: false which continue to build the image using older mediatypes. There is still runtimes used that does not support the new types.

Let me know if you need more from me. I'm usually next to a computer for an easy fix. 😄

I've published some images here to test the changes.

Thanks @MindTooth, sounds like a good idea. Personally I don't know much about this and I don't use it myself either.

Looking at the GitHub Action output it gives an error: "Username and password required"

We're using repository: webpronl/reveal-md (note the extra nl), might that be related?

[MindTooth]

My bad. Just pushed a fix.

[MindTooth]

Hmm. 🤔 Not sure why this does not work. I’ve been successfully using the action myself. I did notice that the username needed to be lower case. Also made sure to use your variable name. Maybe I’ve typed it wrong.

Noticed that org.opencontainers.image.licenses is empty.

Created a test pull request in my own fork, only changed the image name, and was able to login just fine. https://github.com/MindTooth/reveal-md/pull/1/checks

Care to check if I'm using the correct secret names and if the token is not expired or anything?

[MindTooth]

Can you verify that it looks something similar as mine fork?

Looking at this comment from the action itself https://github.com/docker/login-action/issues/236#issuecomment-1179770617.

[webpro]

Yes it that was setup properly I think, but I created a new access token anyway. Trying on master branch now.

[MindTooth]

Something else I need to do for moving this forward? 😄

Let's see what happens now 🤠

[MindTooth]

It works. 🥳 However, it only pushed to master. I don't recall, but that's the correct behavior? latest is last stable release?

[webpro]

Yes, the master branch is basically the only branch. I just pushed a new release (v5.5.0)
