Move analisys scripts to .github folder (#49123)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49123

Previously, we used to have CI workflows scripts in a `react-native/scripts/circleci` folder.
Now that we are not using CircleCI anymore, we move those scripts to the `.github/workflow-scripts` folder.

## Changelog:
[Internal] - Move ci scripts to the `.github/workflow-scripts` folder
