Do not fail superseded Maestro Cloud runs (#58422)

Summary:
Treat Maestro Cloud uploads stopped by a newer upload as successfully superseded instead of failing the GitHub Actions job. The action still fails the job for test failures, timeouts, and errors, including failures where no upload status is available.

This allows the Maestro Cloud “Stop Previous Flows” setting to be re-enabled without creating failure tasks for intentionally superseded runs. Re-enabling that project setting remains a separate dashboard operation.

## Changelog:

[INTERNAL] [FIXED] - Do not fail CI when a Maestro Cloud run is superseded

Pull Request resolved: #58422

Test Plan:
- `git diff --check` — passed
- `./node_modules/.bin/prettier --check .github/workflows/maestro-cloud-rntester.yml` — passed
- Exercised the result gate for STOPPED, ERROR, missing-status failure, and SUCCESS outcomes — passed
