Where is this list from?

From the official API.

SteamKit2 is considering reintroducing a bootstrapped list (SteamRE/SteamKit#597 (comment)). If they do, I'll use their list. Otherwise I think I'll get rid of servers.js and use cm0.steampowered.com (which works most of the time) by default and try to make it clearer that one should really handle the 'servers' event (as if the code in example.js weren't enough).

Thank you for your contribution. I chose a different approach in 8f0f68b. Instead of hard-coding a server list, it is downloaded automatically when installing from git and is (will be) bundled only in the npm package.
