Deployment was failing, and the dependencies used for it are third-party and of questionable efficacy.
This PR updates CI to use Heroku's own CLI, which is bundled with the Github Actions Runner, and Git deployment. This is less likely to be fragile, as the CLI commands in use have remained stable for many years.
This change also restores deployment traceability to within Heroku, as deployments are now linked to Git commits.
