Does this mean that everytime I set a new label (i.e. any label), the "latest" tag will be moved and a release will be created? This is not intended since sometimes I apply some labels to some intermediate states of the code. I do not want the "release" label to point to that tag.
How can we solve this?

I just saw that you already filter the tags by "r*". So I only have to make sure that the inofficial tags do not start with an "r", right?

This will make the release process slightly different (mainly the latest tag will be set automatically).

So you mean that instead of tagging the repo and afterwards move the latest tag -> now I only set the release tag and the movement of the latest tag is done automatically? So it means that I have less work to do (which would be good :-) ).

Yes. That's the case

Yes.

In theory macOS and Windows builds could be possible with GH actions too. But I haven't managed it yet (and would like to focus on one OS first)

Great, thanks.

If you could figure out how to do it, that would be great.
