Add game version to games resource endpoint

[stuffyerface]

Currently, the games endpoint shows information on all games including name, modes, database name etc. At the moment, the only game which has its version displayed is SkyBlock (in a roundabout way through the collections resource endpoint). I am suggesting adding a string of "version" under each item in "games".

The reason for this is that the SkyBlock version data is already very frequently used, and other games would be useful for the same reasons: checking for updates, distinguishing between major and minor patches etc. Additionally having them all in the same place would be useful, either under /resources/games or /resources/gameversions or /resources/games/versions.
