Nope. The content is served through Steam, not on the page. You’ll have to find someone who mirrored it if it’s been taken down.
Edit: however, if it’s still available in the Steam CDN system, you may still be able to download it with a tool like this: https://github.com/SteamRE/DepotDownloader
The only required parameter is the appid, which is in the page URL. I don’t really know what the other IDs are, but you can mess around and see if it works.
