Fix post-release workflow failures (#57627)

Summary:
Fixes the three post-release failures from the [0.87.0-rc.2 publish run](https://github.com/react/react-native/actions/runs/29775529785/):

- Keep Flow annotations in `verifyArtifactsAreOnMaven.js` as comments so `actions/github-script` can load the file with plain Node.
- Pin the Podfile lock workflow to `macos-15`, which provides the configured Xcode 16.4 version.
- Use the canonical `react/react-native` owner for release asset API operations so upload POST requests are not redirected from the former owner.

## Changelog:

[INTERNAL] [FIXED] - Fix post-release Maven verification, Podfile lock, and release asset jobs

Pull Request resolved: #57627

Test Plan:
```sh
node --check .github/workflow-scripts/verifyArtifactsAreOnMaven.js
node --check scripts/releases/upload-release-assets-for-dotslash.js
yarn jest .github/workflow-scripts/__tests__/verifyArtifactsAreOnMaven-test.js scripts/releases/__tests__/upload-release-assets-for-dotslash-test.js --runInBand
```

13 tests and 15 snapshots pass.
