Automate checking for artifacts on Maven (facebook#50275)

Summary:
Pull Request resolved: facebook#50275

This change adds a check to automate a step in the release process: https://github.com/reactwg/react-native-releases/blob/main/docs/guide-release-process.md#verify-assets-have-been-uploaded-to-maven

The script will poll maven for 90 minutes and return when the artifacts are available. If, after 90 minutes, artifacts are not available, it exits with code 1 that should fail the Release workflow. The Release Crew should have a look at what's happened.

## Changelog:
[Internal] - Automate the check for artifacts being on Maven
