Updates to use GoReleaser for Docker images

GitHub Action:

* Deleted docker relase action in favour of using GoReleaser for Docker too
* In the 'release binary' ...
  * Renamed to more generic 'release.yaml' as we do more than the binary now
  * Removed 'skip announce', as we haven't got anything configured,  added skip flags for homebrew and docker
  * Added the steps required for Docker builds in GoReleaser

GoReleaser config:

* Updated to add docker config for multi-platform builds

Dockerfile:

* Drop version arg and push via pipeline in GoReleaser for label metadata
* Allow more env vars to be used to configure log path, config and runtime fiile

docker-compose:

* Ditched .env file as it's required if you don't want an error
* Ditched 'args' as unneeded, matched the env vars  and defaults with Dockerfile for clarity
