Total downloads does not count all releases

### Are you experiencing an issue with...

shields.io

### 🐞 Description

The number in the total downloads badge for our repo has been fluctuating lately. We believe the issue is the badge is only counting downloads for the most recent 500 releases, instead of paging over all API result pages for every release.

### 🔗 Link to the badge

### 💡 Possible Solution

Iterate over each page of the GitHub API call results using `per_page=1000` and `page=N`.

I think the issue is here: https://github.com/badges/shields/blob/23c0406bedfc6930735e8f5ea75dfe34faf1f290/services/github/github-downloads.service.js#L246-L251

Start by reading services/github/github-downloads.service.js around lines 246-251 and inspect how the GitHub releases API results are fetched. Verify the total downloads badge for the linked tfsec repository includes releases beyond the first 500 and remains correct when results span multiple API pages.
