Body

Recently (in the last week or two), the GitHub Releases API has stopped showing content for "assets": where in the past it has and where we relied on that information to check if a Release had Assets and could be deleted:

Current broken state examples

https://api.github.com/repos/dev-drprasad/delete-older-releases/releases?per_page=100&page=1

Expected Assets should show in JSON responses

This seems to be affecting our users:
