upgrade base image to debian 12 and tor daemon to 0.4.8.13

[m0wer]

Based on https://github.com/lncm/docker-tor/pull/30 but a bit more up to date. Fixes #13 and #21.

I will mantain the fork in my repo until merged. I've enabled CI to automatically build and publish the images to ghcr.io/m0wer/docker-tor

docker pull ghcr.io/m0wer/docker-tor:0.4.8.13

The ci commit should be removed before merging unless you also want to publish images to the GitHub image registry.
