ci: auto-commit generated Dockerfiles and update README after publish

- Remove /generated/ from .gitignore so Dockerfiles are tracked in git
- Add {{IMAGE_FULL_NAME}} template variable to README.md.template so
  the table header reflects the actual registry (fork vs upstream)
- Update-Readme now substitutes {{IMAGE_FULL_NAME}} from $imagePrefix
- Add update-repo job to publish-fork.yaml and publish.yaml: after every
  successful publish, Prepare + Update-Readme run and changes are
  committed back with [skip ci] — preventing broken Dockerfile links
