Blank screen and 429 Too Many Requests error on Upgrade Helper site

[GabeConsalter]

Bug

When accessing https://react-native-community.github.io/upgrade-helper/, the site displays a blank page, and the browser console shows multiple errors (see attached screenshot).

Steps to reproduce

1. Go to https://react-native-community.github.io/upgrade-helper/
2. The site displays a blank page instead of the expected upgrade diff.
3. Open the browser's developer console.
4. Observe errors like:

   GET https://raw.githubusercontent.com/react-native-community/rn-diff-purge/master/RELEASES 429 (Too Many Requests)
   TypeError: Invalid Version: 429: Too Many Requests
   

Describe what you expected to happen:

• I expected the Upgrade Helper site to load normally and show the React Native version diff information and upgrade steps.

Describe what actually happens:

• The site shows a blank page.
• Console displays multiple 429 (Too Many Requests) errors trying to fetch RELEASES file.
