IPCR Forge page: fix the publish guide after a run-through

Following the page end to end on a fresh demo box found four gaps:
- rad init needs a Git repository with a commit: show git init/add/commit
- the node must be running: rad node start
- rad seed ends with "✗ Target not met" from the public seeds; harmless,
  check the Radicle explorer instead
- the first build takes 5-10 min while the runner pulls its images
Also say to commit the workflow before tagging.
