Summary:
This local change adds a script to poll Maven automatically after the release has happened.
This should allow the Release Crew not to repeatedly and manually refresh Maven urls in order to see whether the artifacts are there or not.
As soon as this job is green, artifacts are out!
Cost wise, we are using a small machine, which costs 5 credits per minute.
## Changelog:
[Internal] -Add script and CI job to poll for maven after a release.
Pull Request resolved: https://github.com/facebook/react-native/pull/38985
Test Plan:
Tested locally, running the JS script.
[Verified that the CI job can execute it.](https://app.circleci.com/pipelines/github/facebook/react-native/29634/workflows/5966d5f9-12ca-40b1-9185-758fe98d3aee/jobs/944107)
We can only test this for real while doing a proper release.
