Publish and advertise official container

[ssbarnea]

Distributing weechat as a container should become the recommended way to run it. Still at this moment we only have this repository which is used to build containers, not to publish them.

• configure pipelines for building
• assure containers endup on docker.io and quay.io, both have ability to automatically build containers, so a GHA push strategy may not be required.
• advertise containers on weechat main page and https://weechat.org/download/ one

Hi @ssbarnea,

Yes for now, nothing is automated.
I thought that with 3/4 version per year, I could still do it manually, but I'll check to automate this.

Adversiting on the containers, yes of course, once they are available.

Recommending to run weechat in a container, I'm not for. What's the goal behind? Using packages from distributions or compiling sources is for me the right way to use WeeChat. Of course container is just an extra option, but I don't get the point to recommend this by default.
