ci(release): un-ignore tauri.conf.json + fix updater-json input

- tauri-action globs for tauri.conf.json honoring .gitignore; the global
  *.json rule hid it (force-added but still ignore-matched), so detection
  failed with 'Failed to resolve Tauri path' and it tried to re-init.
  Negate it like the cuda overlay already is.
- rename uploadUpdaterJson -> includeUpdaterJson (valid v0.6.2 input).
