fix: Remove caching from GitHub actions to allow compilation of docker container

The GitHub action `actions/cache@v2` is no longer available. Last successful docker build was 2024-11-15

I've removed the caching, as merely upgrading the version of the cache script did not fix the problem. Since the revoltchat/revite is deprecated I believe that the lack of caching in builds shouldn't be an undue burden on GitHub. Only 9 commits have been made here since builds stopped working

The logic for publishing Docker containers has been shuffled so that the build is executed only once when publishing.

I have tested building to GitHub's container registry, but not to dockerhub, I do not forsee any issues there.

Main reason for doing this, is that a fix for attachment downloads (https://github.com/revoltchat/revite/pull/1067) is not easily available to anyone running self-hosted.
