MapPack links fail to download in Chrome

While attempting to download the Map Packs in Google Chrome when the hyperlink is clicked the browser does not allow for the download to be made with the following error:

```
Mixed Content: The site at 'https://github.com/' was loaded over a secure connection, but the file at 'http://blzdistsc2-a.akamaihd.net/MapPacks/Ladder2017Season1.zip' was redirected through an insecure connection. This file should be served over HTTPS. This download has been blocked. See https://blog.chromium.org/2020/02/protecting-users-from-insecure.html for more details.
```

This might bot be an immediate issue but it gives the notion that the URLs might not be working at all.
When the links are referenced directly from the source code of the website there is no problem with downloading the maps.

Locate the Map Pack hyperlinks and the referenced http://blzdistsc2-a.akamaihd.net/MapPacks/Ladder2017Season1.zip URL in the website or source references. Test the link in Chrome and verify that the Map Pack downloads without the mixed-content error when served through HTTPS.
