Deploy a stack with dnode from any repo, so no repo copies the dnode setup

+# dnode-deploy
+
+Deploys a stack with [dnode](https://lab.zlymeda.dynu.net/go/dnode) from a Gitea workflow, pulling the newest images. The runner needs `dnode` on its path (`go-executor` has it).
+
+The `go` org already holds `DNODE_CONFIG`, `DNODE_KNOWN_HOSTS` (variables) and `DNODE_SSH_KEY` (secret), so a repo there needs nothing set up.

+```yaml

+        with:
+          stack: goodwe
+          nodes: hp1 hp2          # or 'all' (default), which can roll out with health checks
+          deploy_tag: master
+          dnode_config: ${{ vars.DNODE_CONFIG }}

+          ntfy_token: ${{ secrets.NTFY_TOKEN }}
+          ntfy_failure_topic: ${{ vars.NTFY_FAILURE_TOPIC }}
+```
+
+`nodes: all` deploys to every configured node, so use it only for a stack that runs everywhere; name the nodes otherwise, as a node without the stack fails the deploy.
