Limit the number of initial build targets

- Start-off with just two build targets.
- Cachix is pending subscription, remove the cachix cache while we
  don't have it yet. We'll add it back later.
- Rename the cachix authentication token. We don't have the token yet,
  but once we do, we'll add it by the name of 'CACHIX_AUTH_TOKEN '.
- Remove 'workflow_dispatch' event from the workflow triggers, to
  not allow manually re-triggering the action.
