Builds the image and pushes it to ghcr.io/uio-gaming/mustafa, tagged with the release version and latest. It runs as a job in the release-please workflow, because releases created with GITHUB_TOKEN don't trigger other workflows.

The old workflow ran docker compose in the repo folder, which failed because the containers belong to the server's top-level compose project. The deploy key can now only run /usr/local/bin/uiogaming-deploy (see UiO-Gaming/drift), so the workflow just passes the service name. Also adds manual runs and prevents overlapping deploys.
